6 7L POWERSTROKE CATASTROPHIC ENGINE FAILURE

DISASSEMBLY AND DISCUSSION OF WHY THESE ENGINES FAIL

With age comes wisdom. I bought a 2000 7.3 at age 19 and stacked a bullydog chip with an edge evolution tuner. Six months later my tranny was gone and so was $3,200 for the repair. I'm 31 now and my (I'm the owner) work vehicle is a bulletproofed 6.0 that is bone stock except for exhaust and an intake. Eventually, we learn that pushing an engine leads to an empty bank account. If you want to go fast, an 8,000lbs truck is not the answer.

[@skigdividerx4991]

Another good video Bill. I've worked for a Cat dealer for 25 yrs and built engines for most of that time. The bottom end of the 6.7's look a lot like the old 348 and 349's. They were overhead cam V12 and V16 engines. The over the road truck drivers always had to have more power and more power! The old 3406's took a lot. These new engines are incredible and at the same time crazy! I'm not sure about going back to a water cooled aftercooler but they are smarter than I am. Thanks for all the great info!

[@theq4602]

Read a story once about how a guy put a 3408 in his f350 (he was wery wrich) he then proceeded to have it modded to get a lot more power than it was designed for. It sat most of the time he owned it. Every time he romped the throttle it twisted the crank.

[@richardvandyke9578]

3408 is a huge engine and would never fit in a F350. You are probably thinking of a 3208 which would still be a tight squeeze.

[@theq4602]

Whatever it was it twisted his drive shaft alot. lol

Hey Bill. I just want to say Happy New Year and thank you. I am a pro tech with 30 years under the belt. I am a scope and scan guy who never sees diesel stuff. When I do it is a learning curve. The information you give out is greatly appreciated. When I first saw what you did with the heads I was BLOWN away. That steel O ring should be done from the factory. You know your shit sir. Well done. Very well done.

[@hgffrank]

Career Ford diesel master tech and FCA/GM tech here. While this guy makes some valid points, I respectfully dissagree with his philosophy. Not all people delete and tune trucks to have "industrial diesel phsyco tune" kinda power. Many delete and tune for reliability and service life.....tuning and deleting does not in and of itself destroy an engine. An intelligent driver who deletes and tunes a truck will in FACT lengthen the life of the engine. I personally own a 2012 F350 6.7L.....I have 11,291 engine hours including 5,906 idle hours. This totals 254,604 actual miles. My truck was in the oilfield here in the desert of NM for the first 121,000 miles of tough operating conditions, however as the mechanic who performed all the work on the truck, I knew it had been maintained well. When I purchased it I drove it about 6 months in stock form, mileage was terrible, power was just ok. Cost of DEF piss and hassle was ridiculous, and constant regenerating around town was a constant irritation. Considering that the majority of repairs I've made on th 6.7L are emissions related, its an obvious weakpoint in design. Just another case of government destroying perfectly good engines. Its obvious this guy is all for government regulation and throwing money away which is exactly what the emissions systems on these trucks accomplish. The emissions debate is never ending and I'm not here to sway anyone away from being environmentally responsible. Just think for yourself and come to your own well researched conclusion. I personally am of the opinion that modern emissions system are more detrimintal to the environment than helpful. You cant consider only the environmental impact of the truck itself, but also the impact of parts producation, logistics, maintenance, and as of the recent years the continuous impact of production of DEF and the waste stream produced just from that. California wants to ban straws but has no problam mandating plastic constainers that contain enough plastic for 5,000-10,000 straws....liberal ignorance at work. Also consider the massive loss of fuel economy due to emissions that result is massive additional crude oil usage which also has a significant environmental impact. My particular truck was lucky to get 24mpg on the highway and 14 in town. I could jump in my truck today and drive across the country and see 28-30mpg, and in town I now get 17mpg. If I baby it I can easily achieve 32mpg and thats with a 80 gallon fuel cell in the bed full. I have towed approximately 60,000 miles at or near max capacity. I have never opened the engine for any repairs. Truck still runs like new. Its my professional opinion that a deleted and tuned truck "PROPERLY" driven is far more durable and long lasting. #1 Never mash the throttle. Diesel engines have heavier parts and rate of rpm increase that is slower will lengthen engine life. Always roll into the throttle slowly, especally from flat idle. If you hear ANY type of pinging you have accelerated too quickly. If you see smoke exiting the tailpipe you have acclerated too quickly #2 Just because its tuned and deleted does NOT mean you have to be a jacksass rolling coal every chance you get or at the sight of a Prius.If your rolling coal you are damaging the engine and wasting fuel, with the added affect of looking like a jackass and damaging the reputation of diesel engines and truck owners, which certainly does not help our cuase at the government regulatory level. A 3rd point I'll make is that maintenance is HUUUUGE on these engines and vehicles. Never go the factory interval on the 6.7L and never use 15W40 oil in a 6.7. I've seen far too many turbo failures on engines running 15W40 to know there is a correlation. I personally recommend only 5w40 synthetic. Adding a bit of zinc additive is also a great idea. I do not believe younger people should have delete/tuned trucks but those who are older, wiser, and more responsible I dont see any problem. As for this youtuber's claim that dpf delete voids a ford warranty, I'll say as a Ford master diesel tech that he is absolutely full of crap. Only modifications that directly result in a failure are denied warranty coverage, and the modifications do not void the warranty as a whole with the exception of catastrophic engine damage that is due to a tune. I admit that is a reality, however that goes back to the way the truck is driven. I have performed warranty repairs on many diesel engines that have been deleted and tuned. If its not directly related its not an issue. This brings back a memory of a customer who brought in a truck with one of the supposed emissions legal tuners installed like the youtuber proclaims is gods gift to diesel trucks. I wont name the brand, its not important as they all have the same basic philosophy thats used to write the tune. This customer had a low power complaint. I looked at the truck and found the dpf was plugged nearly completely. I managed to save it, and instructed the customer to remove the tuner. The fool took the truck, and he pulled the tuner out of the truck and then came back with the truck on the hook for a no start. Diag found the dpf completely plugged, I asked the customer why he didnt remove the tune, he claimed he did, but I knew he just removed the tuner but never set the pcm back to stock. His dpf warranty claim was denied. In no way was his engine warranty effected. Of course you will run into super-techs here and there who feel like its their job to regulate and nit-pick every little thing just to try and void a warranty with the thought that it will then become a customer pay repair thus making them more money. I am a six figure tech without the desire to shaft the customer without reasonable consideration.

The 6.7 is pretty bulletproof from people I have talked to but some I have talked to also have agreed to that as well. Love the videos and they have helped me in the planning of my engine swap as well.

I had to convince him to trade it in on a 2014 Ford Transit Connect titanium. I spent $15,000 on 3 repairs always concerning injectors, EGR cooling system and related items.

You have a great channel. Most mechanics would never go this into detail

[@thomabb]

Your question at 10:50 - "Did the rod fail first, or did the piston fail first?". The failure of the rod is at an angle that would suggest propagation of a fatigue crack. I would bet a dollar the rod went first.

[@upurnose46]

I would bet the rod went first too because if the piston went first wouldnt the rod still be intact?

[@pdx650]

Excellent video, Mr. Hewitt. My fiancée and I purchased an F350 to tow some trailers around. After going through your videos, website, and some other KZbin channel videos regarding the 6.7 "Scorpion" engine in our 2013 (mfr date 12/12), I've come to realize we avoided the dreaded the ceramic-coated bearings in the turbo. I hear that is a good thing since they have been known to disintegrate. There are supposed to be steel bearings in this years' (2013) turbo. We purchased the Damerow Ford-Dealership truck (located in Beaverton, Oregon) with 64k miles on the odometer. It is the platinum trim level. Unbeknownst to me, the center console between the two front seats is permanent. I think we will be getting a trim level that has seating for 6. Why did Drew Bledsoe (former nfl QB) need to get this truck with this trim? I don't know, but we have his old truck and will be trading it in for a different one.

[@timothygrable2099]

Bill, well said on tuning these trucks. I have a 2011 and a 2016. 16 is bone stock ( work truck ) and my 2011 is my POV. I have tried different tunes but the key is to stay close to stock numbers and leave the emissions there. DP as he said is a great company for tunes, I also recommend AM Diesel Performance and 5 Star tuning. All of them have great Emissions on tunes and will work with you to make that tune feel right to you. Shifting points, times and lengths are the most complaints on tunes. All 3 above have great starting points, but will tweak them to your liking. Don't go kill your trucks for crazy power, when these trucks are awesome enough as is. IF you do want to go crazy, you better start upgrading internals. If you don't and you break it, don't go blaming Ford, Its on you.

[@keithknowles8899]

What exactly does the "we build a better motor than Ford" comment really mean? (seems really odd especially how he leans into the camera). I drive a completely deleted 6.7 with H&S tuner (they are not out of business as others have commented) and it is clearly stated all over the place that towing should only be done in tow mode (NOT IN PERFORMANCE MODE). So, the guys who owns the truck in the video (did not service tranny, did not change oil at regular intervals, pulled a heavy load in performance mode in his tuned truck) and from that we are supposed to believe that all tuned and deleted motors will end up with same fate as this motor? Also, in the video they state that you cannot run DPF delete because of the timing. What does having the computer over ride seven DPF sensors, have to do with timing. There is a stock setting on the H&S tuner that does not adjust the timing for any performance gain, it simply tells the computer not to throw error codes for all the disconnected sensors from the deleted EGR and DPF. I understand that they have improved the cooling system so that the super heated exhaust in the EGR is cooled more sufficiently now as it is brought back into the motor, BUT why do you want "heated used air" going into the engine. Cool, clean, fresh air makes any engine run more efficiently. Has anyone ever cut a DPF apart? HOLY BACK PRESSURE BATMAN, cut mine up and sent it to some guy on internet who harvest the platinum out of them and he paid me $275 for it and paid the shipping. You need the damn turbo just to force the exhaust thru all the crap that is packed into the beast. All motors BUT especially diesels want to breathe to run more efficiently. I am not claiming to be any type of expert and I am open to correction if any of comments here are incorrect, just simple observations from a simple guy. Who is damn happy and proud of his 6.7 (please pardon all spelling and grammatical errors as I said before just a simple guy here)

[@Victorbanda1234]

+keith knowles My dad has a 6.4 that he has had deleted for the last 12,000 or so miles and the truck has been great way better with out the bs restriction it has before deletes, Its up to the owner to understand what power can do to ones truck, even if you run in performance but drive conservatively i would bet you will be ok, and towing is obviously for towing, thats what it was designed for any owner should know that, maintenance is also key in owning a heavy duty truck, Completely agree with what you are saying on everything.....

[@KBS117]

I agree.. That truck had static lock due to a bad injector... This guy is selling...what he is selling, is his tuner... He thinks he is slick and we will fall for, some idiot pulled in performance mode...I have an 03 6.0 crew cab dually, with 600k on it.. Put the edge with juice on it at 25k miles.. I have had it in level 5 (kill mode) since install.. It is my work truck.. I installed the egr butt plug, when I installed the tuner.. No egr delete, nothing else has been done.. It will smoke all 4 rear tires like a dragster.. This guy needs to blow smoke up some one else's ass..

[@Hudbudd]

KBS117 He was talking about 6.7s. 6.0s are not even in the conversation, they can be built to 7.3 quality through him.

[@wagonerjared]

Point well made. I run H&S tuner on my deleted '11 6.7 PSD on street mode and it runs great. Tow mode when I tow. I don't use the performance tune as I am 38 and don't need that shit. I change oil at 4k and run a quart of Lucas synthetic and oil analysis through Blackstone every service.

[@kenl4929]

100% agree, tuning. Not saying too much tuning, but Bad trans tuning. In my opinion, the root cause is from Lugging w/too much converter lock up. That giant tune feeding those conditions....Massive amount of stress & heat generation! Then any microscopic impurity in that piston casting will show its face real quick. I think you're right on your assumption of piston failing first! You're the man! Your videos rock! (Diesel mechanic 20yrs running)

[@jwillrett9182]

A mini maxx is one of the best options for tuning.. "a mini maxx has too much timing"? There are many different options for custom tunes through a mini maxx that are very safe to run with out a doubt. There are a one or two companies that really try and push an unsafe amount of power but that is not due to the H&S unit itself, that is due to that individuals tune files. Tuning these engines with out deleting the dpf is useless as well. The amount of emissions would increase with the dpf tuning on, and there for the dpf/scr would work harder to "clean up" the emissions and the dpf filter would clog/fill up quicker. With the correct custom tuning, a 6.7 with a stock bottom end will hold up to 650 generally. All about bringing the power on smoothly.

Sometimes, you pan through the grenade aftermath, and I can't even determine what part is what. Just a pile of kibbles and bits. Not asking for an hour movie, just slow the pan down a touch!

Is there any solution to keeping this urea from freezing or just getting rid of the urea system alone?

Bought my '03 F350 7.3 used at 155k miles about 6 months ago. Had a TS-6 position chip in it. First thing I did was yank that tuner out. I really want to run this truck another 15 years/150k miles, at least. Kind of sad to see what's becoming of these newer 6.4/6.7 trucks. Emissions is killing them, and the tuning to run em without emissions equipment is killing them too! Damned if you do, damned if you don't.

[@jamesmartin9668]

I agree. which is the recommended path?

[@JamesSmith-ho7kg]

I think what he's saying is by itself the 6.7 is a killer motor but because of the CAFE standards ford had to add the DPF to meet the emissions and fuel economy standards. If an owner deletes the DPF some other engine tuning is needed so the motor runs correctly. Most plug in tuners adjust the timing needed when the DPF is deleted. Again I'm no mechanic but that's what I gather from the conflicting statements.

[@chuckconet5295]

James Smith Im with you...Id just feel better if he would say it...(he dont have to condone or endorse it, because we know it is illegal)...just clarify it

[@ericferguson4114]

Deleting the dpf is the way to go period. If you drive it with some decency you won't be blowing it apart, even if you're running the hot tune. You'll be safe running the stock power tune or a tow tune. It's all in the operator. Lots of guys run the hot tunes without problems.

[@Marine19571966]

Hey, bud. There is no "explosion" in the cylinder during normal firing - the fuel-air mixture only "burns" with a flame-front velocity just below the speed of sound. Should the mixture be too lean and the flame front exceeds the speed of sound, then you have detonation (explosion) in abnormal firing which melts the piston.

What about running the deletes with a mini maxx tuner still on the stock level tune for those just wanting better economy and not have to add urea?

[@gwhunter07]

Im sure it will be fine as long they keep it around the stock level tune. This guy was probably on performance tune with a trailer in tow. Big no no. The performance tune increases the timing and pressure inside the cylinder. Pair that with a heavy load and increased pressure on the engine and it goes boom.

Sad to see the newer diesels not holding up. still running my old 96 7.3l with mild upgrades. it can still raise cane with the new trucks. we even dodges. it may be a log wagon dinosaur, but it gets the job done without the drama of the 6.0, 6.4, or the 6.7.

[@Ruger41mag]

Thanks for breaking this down for us dummies - poor maintenance, poor operator technique, poor tuning. I guess if I take care of my 6.7, operate it conservatively and within the specified Ford operating parameters, and don't tune it, it should last a loooooooong time.

[@yamaharidr450]

+BangFlop No it wont. Keep it factory and expect to put a motor in it at 200000 and putting a new exhaust on it at 100K when it gets clogged and cant flow.

[@Martin-tb4oo]

Awesome videos!!! I am addicted to all of them. I don't own a power stroke, but I am a huge fan of them. It is kinda disheartening to watch these videos and see that even in stock for you are driving a ticking time bomb.... I want to buy a new f450. What am I supposed to do pay 75k and stick another 12k into it for piece of mind? What's the point of buying it then.... Why has Ford for sake it's most loyal customers..... 😔

[@xX_Kryptis_Xx]

I don't even own a truck but I like this guy! he knows what he's doing

[@paulhyland5868]

I'm glade we dont have emissions in TX.

[@Willyd2758]

Glade like the air freshener?

[@SubieRow]

Texas has emissions. As well as yearly safety inspections. That's why I won't move there. Going the way of commiefornia

[@rickreid81]

Thanks for all the great info. I don't own a diesel but I always learn something listing to you. Thank u for the performance information!

[@whilomforge3402]

I bought an '11 back in 2012. It had 18k on it, Florida truck. Loved it from the beginning, then at 20k the egr went along with basically the entire cooling system. Tons of front-end work and 5k miles later, the turbo crapped out. Went through two new turbos and just about every sensor under the hood. Luckily, Ford was more than helpful, however, if I ever buy another powerstroke I'll damn sure bring it to Bill.

[@jeffreyguild1032]

I change all the oils when the truck tell me too .Its a 2016 F 350,Next oil change I want to go Amsoil full synthetic it has 30,000 miles but I need to know can you go without changing the oil for 25,000 miles with synthetic oils

[@kevinoneill41]

I know this is an old video. But lets talk tuning. If you want a race truck build a race truck. These are not race trucks. I put my tune in to delete a failed science prodject in the early emission control of my 6.4. PS my 6.4 is still running. I put a Mini Maxx in i know you'll say I'm crazy. I set it at tow, lowerd the low boost fuel to the #2 setting and unpluged the tuner. I had to replace the new stock cold air intake to a this is just my desision S&B filter system. Because when I pulled out to pass someone the replace air filter light would come on. Now I know these engines need to breathe. But having a stock air box with this much restriction is just not right. I get no black smoke on lift off in stop and go traffic. When im pulling my 30ft trailer or the work trailer or if I'm just going back and forth this setting has not caused me any troubles and is plenty quick. Now this is Aug 2023. And another 100K down the Rd. PS i bought this truck for body stile she is a beauty its what a truck should look like. Now if some one could fix the blend door isue I would be very happy

[@mckinzi1]

looks like about 6 lawnmower motors someone ran E85 in whoooopeeee 2 stroke Dura Force Lawn Boy was run with 50:1 rather than 32:1 mix and the rod twisted kinda like the one you showed there. bout this close to coming apart...rtfm folks

[@wisetow10]

If H & S is no good then who is the best aftermarket tuner to use for those of us that don’t have a tuner in driving distance?

[@matthewnelson3578]

But you kind of say it's okay to delete the DPF and EGR on the 6.4 truck, which I did on your recommendation. I run a Spartan tuner with the DPF/EGR off, stock tune. How is it different for a 6.7 vs a 6.4?

[@svt89]

Man thank God for EFI live tuning for the Duramax and Cummins ! And those are some tiny ass rods for a diesel lol .

[@Mikefngarage]

damn I cant hit the like button twice

[@chevyblock550]

Mr. Hewitt, not to question your experience, but wouldn't a failure like this with the piston, rod, camshaft, lifters, etc. be from high RPM instead of the tuner? I would be led to believe a tuner that has a lot of timing would cause high EGT'S which would lead to a valve train failure from premature wear, not in the bottom of the motor.

[@jeffreyguild1032]

I like your videos I have a 6.7,I use it to haul my 27ft RV

[@jasonman1515]

powerstrokehelp, once i get my diesel. I have couple more years to save up, not to mention love the new style coming out, I'm going to send it to you and want you to pretty much bulletproof the shit out of the engine. Make it reliable unlike some of the videos i have been seeing on youtube.

[@mauipalmandtreecare]

we pull a 7,500lb wood chipper with our 6.0 F350 no tuning just EGR delete with onyx head gaskets and ARP studs. she gets regular maintenance and oil changes. good good truck!

[@deanmeyer1815]

Great video! Tons of great info. That's pretty crazy that Georgia police will impound your truck!

[@vegasfordguy]

Great info as always! Enjoy the straight up no nonsense talk.

[@kandiland6571]

I have a question for all the geniuses on this awesome Channel.I have a 2015 f550 6.7 4x4 with no more than 5000 pounds of tools and stock, I am a mobile truck mechanic and I do a lot of Pull starts. My question is am I abusing my truck by doing this? If possible I unhook the trailer sometimes this is not possible due to not able to release fifth wheel pin, I am able to do this with pretty much no effort unless on a upward grade then just a little more effort to get moving never spinning the tires.I usually only pull the truck 5 to 10 feet to start it. The truck can weigh up to 80,000 pounds.It pays $350 each time hard to say no

[@AdamH108TA]

Great Video, Fascinating once again. I don't even own a PSD truck but one day I hope to. (they are very expensive here in the U.K) Keep up the good work Bill. From Adam in Scotland, U.K.

[@wuzgoanon9373]

They are very expensive here, too.

[@brian6265]

I personally LOVE the old 12v Cummins as well as the gen 3's 24v pre emissions. but I'm wondering. labor and parts. what does it cost to bullet proof a 6.0 so it'll last forever.

[@abelwrate4330]

brian6265 $7,900 Bullet Proof. He also sells Bullet Proof Transmissions from his contact.

[@volvo09]

another great videoHere's a thought I've had as I've run into more and more quick diesles out on the road... With all the luxury and features these diesel trucks offer nowadays do you see your shop getting more "inexperienced" diesel owners coming in who have never owned a diesel before and break them trying to run them like a gasoline / spark engine? like revving the crap out of them or just slapping a tune on and not worrying about how hard you run it because "you don't have to worry about detonation" for instance? I see a lot of nice fast trucks out on the road and I can only imagine quite a few of those have been playing with fire by running a race tune on a stock engine.

[@livalittle100]

See the thing is having a fast truck is to cool. It is such a special feeling when the turbo or turbos light, if it hooks it slams your neck back into the seat, if it doesn't hook it turns the rear tires into a smoke show. Either way it is so much freaking fun! Thats why people do it.

[@walkerforsyth6221]

livalittle100 These so called people have obviously never gone for a ride in a fast car

[@everettclunie3525]

And these are the results! Gotta pay to play!

[@fordrac1ng81]

I do it on a $5000 motorcycle. My trucks are work vehicles. My bike will beat 99.99999% of trucks at 1/100th the cost per mile.

[@nebeerz]

Loose nut behind the wheel. Love it!

[@livalittle100]

So when the timing is advanced too much it destroys the bottom end of the engine? but I am assuming that there is an amount of timing advance that will not hurt the motor but still make more power?

[@canton7180]

If stock internals can't with stand hot tuning and that is what the owner wants, aren't there after market internals available that are engineered for it, I mean if you take a n/a motor and boost it you 'll usually replace the internals with forged parts, at least that is what I do anyway.

[@brucewillson3854]

not a powerstroke specialist but thats gotta be atleast 15 grand lol. my cummins has been pinging lately but ive put a couple thousand miles on it since the sound started and im not worried. plus if it blows ill put a new one in for 5gs or less

[@iancampbell582]

You got a nice shop space fella.

[@volvo09]

Love the lessons here. Luckily I learned with cheap cars when I was young.... can't imagine spending 40k on a truck and grenading the engine. I supercharged my car 4 years and 80k miles ago - 16 year old me would have destroyed it already showing off.

[@scottclemens7025]

Why are the bolts for the vacuum pump 89 in/lbs? I'm sure many PS owners are asking that. Shoulda been a recall.

[@weldreth24]

what about a dpf deleted tune but on a towing tune not a crazy 250hp tune ?

[@patw52pb1]

Bill, are new bare block castings available for the 6.7? Every failed 6.7 I have encountered so far was user and or tuner related. We have a 2012 6.7 with over 200K on the clock and outside of factory recalls and regular maintenance have experienced zero issues. Thank you for all that you do.

[@adrianspeeder]

Kibbles and bits! So it's a good idea to keep the DPF on a 6.7L? I ditched the DPF on a 6.4L to keep that heat from killing the top end. Only daily drive the 150hp to keep the clutch happy.

[@reedwunderlich8370]

With the separate cooling system on these trucks for the emissions does this take the heat out of the engine more effectively than one huge radiator like on a 6.4 ? An Egr still puts hot exhaust gases back into the engine which I cant see being good for it and can only be removed with tuning? Are you saying 6.7 owners should leave the trucks with emissions still in place because there is not safe tuning out there for these trucks to be deleted with yet? or the cooling system is substantial to dispersing the heat out of the engine with out damaging anything over time? Or leave these trucks stock due to the legal aspect of it? Its illegal to delete a 6.0 or a 6.4 put we know the consequences of not. Thanks for the video!

[@mitchsnyder7514]

powerstrokehelp Just curious what does a motor cost on a 6.7L like the one here in the video. I have heard they are insanely expensive but anything fomoco is insane. What would a part build motor run?

[@dickgoesinya3183]

you say the connecting rod pulls down on the piston.....id think out of the two strokes the power stroke surely doesn't and the intake stroke is minimal due to boost. id lean more towards high rpms and over fueling with timing too advanced....a good reason to squirt water!

[@GeorgeSemel]

I can just image what the bill came to, my guess it was north of 15 K! For that kind of money I could spend December thru April on the South Island of New Zealand Fly fishing for trout till I just drop and still have plenty of cash left over to hit SW Montana from May to Oct! It seems to me that if you want to go fast buy a Corvette! A Truck like this, you buy for taking yourself out to the sticks on your hunting and fishing trips! But its his money and you are after all in the business of fixing this sort of stuff! To each his own I guess! I would love to have one with all the things that you do done- with a Camper on it and just see how many of the Nations trout streams I could fish in the next decade! Now all I need is a good boat load of money to make it happen! Oh and Happy New Year!

[@Eric_Broome]

I would be careful claiming that dp tuning won't void your warranty. Maybe your warranty won't be voided but the dealer will not honor a warranty with any aftermarket tune.
