I’m not sure I never disconnected the speed sensor. Unless you’re talking about the vgt sensor? If so you’ll need have that program with non vgt turbo

It in the stock turbo right on top next to the antifreeze line. So you just unplugged it and went on? Did you have any codes after install?

Yes my sensors are unplugged. I had my tuner is not looking for the sensor. You’ll need to have it programmed for non vgt turbo.

Yes I no longer run them. Running 3.73 gears now

@@silvercummins3558 on 35s? I’m thinking of going 4.10 on 37s

Just a side note I did find a new wheel/tire in those sizes that will put me to either the stock weight or slightly lighter.

Right now with the 35s I’m lucky to average of 16 to 18 mpg on highway but I do drive around 75 to 85 mph. With 3.73 and stock tires I was easily getting 20 to 21 mpg

If you’re not towing. I would do 4.10 that would put you back to close to stock

What gear you recommend im running 35’s? Thanks

@@roycelubon3837 I’m still running 35s with 3.73 I like the rpms where it’s at. Times I wish I had 4.10s when pulling my 17k toy hauler. I had stock for bit towing my trailer it pulls well. It depends on what your doing but 3.73 good all around gear. I may pull my trailer 8 times a year I’ll deal with it. Hope that helps. One of my early videos I had 4.30 with 35s way to low.

I wish I did

@@silvercummins3558 from what I can see he's hung his hat

I would say. But if you want mpg stay with stock size tires.

@@silvercummins3558 I've gotta have a little more tire for work just curious if 3:42 or 3:72 would get better mpg with 35's

Ya I still have the truck it got 94k miles on it still the same transmission and all stock. I pretty much drive it on 50 hp tune and baby it. I will hot rod it every once while and I don’t do 6th gear pull. When I tow I will never let tow in 6th when I climbing a hill I will down shift to 4th. When I switch levels settings I will take easy for 30 miles.

It is a tuff call going to 4.10 right now with stock tires 3.73 pull great with 35s it still pulls good. Probably 4.10 might be in the sweet spot cause I had 4.30 gears I did not like it. I pulled slower up this one grade by ten miles per hour still in 3rd gear. Bet if I had stocks size tires it would have pulled in 4th gear. 4.30 gears was great for off the line but it suck going down i5.

Correct

Cause I have second gear lock up on torque converter and different shift points with tow haul. With out tow haul don’t lock up until fourth gear. And the down shifting it unlocks.

@@silvercummins3558 is that just ur tunning or do all lock T.C. in 2nd with tow hall on?

The reason was I didn’t want to tell my tuner all the stuff to make it work with the iron kit and I was going to convert it to manual transmission so I thought it was easier todo with stand alone unit

3.73s and stock size tires doing 75 to 80 I will average 18 to 20 mpg. Towing I love it more power. 35s think was to heavy haven’t tried all-terrain tire yet.

@@silvercummins3558 I’m in Arizona and we have some pretty steep hills ( 7% grades going through salt river canyon )and currently run the 3.42s.I’m torn between delete it or upgrading gears first. Also are you running any tunes like an efi live?

I’m living in Arizona too. Love it here. Yes I’m running efi live. The best thing I did is replacing the vgt turbo went with bd iron horn. EGTs went done drive pressure and power. Gears help a lot deleted the truck helps in other ways. Just remember when tuning got watch EGTs more they will climb easier and training shifts never like stick any more. But I like it cause of the sound. What size tire you running cause my first gear swap was 4.30 gears I hated them.

It says this comment was a year ago but I have the plates in my garage if you’re still looking

I’m still bone stock transmission

I just told anachary that I was going with non vgt didn't tell them that I had exhaust brake cause I called pacbrake that is stand alone unit. Tap two wires on injector harness and plug into the crank shaft sensor. It was hard to choose between s366 or s364 but so far I love it still little laggy but it picks up. Never ran on high tune yet but I think made different in power. I message one guy on you tube with s366 he said was laggy with stock fuel

@@silvercummins3558 Thanks for the info my man! I'm probably ordering the S364.5 SXE iron horn kit tomorrow! 👌🏻

Cuestión for you I don’t need to make any modifications after install the 364.5 turbo ?? The turbo is not to big for the stock engine?

Never Enough I clean the def tank and put fresh def and no never had check engine lights on when I flash it back to stock

@@silvercummins3558 hey boss . I’m actually just about to run my efi live on my 18 . I tried waiting as long as I could . I wanted to put some miles on it but I’m only at 8000 now after 3 years so . Not sure if you still have you”re truck or not but did you do a full exhaust or just delete pipe . I no you said you have to put it back together once a year for smog .

@@neverenough7767 I still have my truck I just installed the piece for the cat back😉

Dont take my word but cummins motor are made to run. To low rpm will put more stress on stuff. When I tow I'll tow 5th gear on flat ground running between 2000 to 2300 rpms doing 65 to 75 on highway just finished 1400 mile trip this weekend. I noticed get better mpg and egt will stay lower

I'm just debating putting 3.73 in my truck . I got 68rfe and 3.42. I tow a 10k camper and lock out 6th gear always when hooked up. I dont tow faster than 67 mph because I'm at 2000 rpm. Truck is bone stock.

@@thestepfather2958 my toyhauler when fully loaded weights 18k. I also have 68rfe I tried nitro 4.30 gears with 35s I hate it it was to low my truck pulled better with stock tires with 3.42. So far I really love 3.73 cause it's not to low and not to high like 3.42. Right now I'm running stock height tires. That's up to you if you want to spend the money. I never tow in 6th and when climbing hill I'll drop down to 4th. There's one hill is super steep in pismo beach area I'll drop down to 3rd I'll stay arkind 48 to 53 mph about 2800 rpm. If you think about it the newer 2019 rams are back to 3.73s

Was this video u posted with stock tires and 3.73 I'm really just trying to watch people's rpms to see where I want to be at. But yes I'm leaning to 373 because the new rams did it. And I just want less stress on tranny. I dont k ow how I feel about running 2800 rpms though. I super baby my truck. It only seems that high of an rpm on a downshift that it conducts itself when towing

@@thestepfather2958 yes had 35s on that video. There guys out there take these stick motors to 4000rpm but they dont last long. Think about diesel generators hold high rpms for days. These motors are tough head gaskets will go with added horsepower. But you'll probably have more issues with emissions stuff. But that's on all manufacturers

Running stock tires now at 70 I'm around 1650 rpm

I was in fourth gear pulling that hill. I didn't care to much for 3.42 but it pulled good with stock size tires. The one thing need to watch out on stock 68rfe is 5th and 6th gears are the weakest. I lock my truck in 5th gear towing my toyhauler on flat grounds

@@silvercummins3558 thank you for your input much appreciated

I know this is an old thread, but I just bought a 2012 3500 DRW with 3.73 6.7L. How did yours do with a fifth wheel? And what weight have you towed?

With the 3.73 the truck pulled good. You could tell it was behind you with having a SRW truck. Air bags help alot and rear hellwig sway bar. I pulled it for about 1 season then I opted for a trade in. Now I have a 2017 long horn long box DRW 3500 with the max tow. 4.10 gears and Aisian trans with the GN , fifth wheel prep and 30k 5th wheel set up. Night and day difference. Your DRW will pull fine. Stay away from atleast 6th. Or get some insurance with having 4.10 gears installed it makes a huge difference.

Yes you just replace the ring and pinion which are the gears and you should do the front also if not when you are on hard surface with four wheel drive you will run into issues

On 1500 the fronts are welded in. This is a 2500 solid front axle

During that video I was running 35 inches tires. Right now I'm running stock tires cause fuel mileage. I had videos of me running 35s with nitro 4.30 gears did not like them. Guess what you are planning to do with the truck with highway speed or just pulling a trailer. With test I have done money I spend in gears on my truck twice my guess with 37s would say 4.10s. When I had 35s doing 80 mph rpms would be around 2200. When I was stock gears and tires would pull this one steep high 3rd gear around 50 mph with 4.30 gears with 35s the same hill I still pulled 3rd gear doing around 40 to 45 mph so I was slower my thinking when I did it all thought would babble to do it in 4th but it's too tall of gear. The nitro gears was noisy so I figured I'll put little lower gear then stock so far I'm happy. My opinion 3.73 for 35s and 4.10s for 37s. Other people would say different some I heard 4.56. For me that is real low. But will have a lot get yo and go.

@@silvercummins3558 ok yeah my stock is the 3.42 aisin trans and all the searching people are saying 373 or 410s I dont wanta be doing 80 screaming at 2500 lol so I'm trying to see what people have experiance thanks for the reply

I hear you my gears was stock with 3.42 also. 37s with 4.10 think you would be fine. 4.30 would work to but the nitro gears was noise and I broke one tooth on the front ring gear so I would not go with that brand. If you can stick with factor gears AAM. When I got my 3.73 gears they where used came off a duramax they run same rear axle pumpkin AAM.

Silver Cummins I’ve got a 2016 6.4 Hemi with stock 3.73 axle and stock wheels. Will be pulling a 13,000lb Wolfpack Fifth Wheel Toy Hauler (11k dry plus 2k loaded up), which is right at the top towing capacity. You’re pulling a 14k Fifth Wheel with the same truck and axle ratios right? Would you keep the 3.73 for occasional towing or swap to the 4.10 gears for 3k more towing capacity? Seems like you’re moving pretty good up that grade. Thanks

Silver Cummins sorry I see you’ve got the diesel with more towing capacity and I’ve got the Hemi. Apples and oranges already. I’m guessing I should switch to the 4.10 for the extra 3k in towing to bump me up to 16k.....

Yes I do every time switch tunes drive it easy for 30 miles.

I have a deleted 2018 2500 and was getting 20 to 23 mpg on the hwy before I put 35's on now I'm 15 to 16 mpg I was wondering if the 3.73 would be better. I have 3.42 now

Not the best running with stocks size was the best I am average about 14 to 15 on highway right now when these tires are done I'm probably going with little smaller and narrow and toyo at2 little lighter think that's big part but I dont drive my truck every day

And I also drive on my highways around 70 to 80 MPH I know when I drive 55 to 60 the mpg goes up never hand calculate that lower speed but I done long trips hand calculate faster speed its average of 14 to 15. The reason I put 3.73 is for towing I tried the 4.30 was not happy with mpg and towing

What is your rpms at 70 not pulling anything?

It is around 1600 rpm

I have 6.7 cummins 2014

Running 4" straight pipe some times I'll put muffler in it and I have tip dump at angle

And when it is straight pipe around 2200 rpm it does have a drone to it but it goes away at hight rpm and lower rpm

Well ended up getting a 30ft Airstream last year and love it , how is the trans holding up ? I just had mine done and just getting used to the trans tune . How do you tell when the torque converter trans locks ?

Injectors 50 Thanks for the info. I didn't have issues with the shifting. After all the testing was not happy noise they broke. Right now I got 3.73. I think my truck pulls better in way. The 4.30 was to low just cruising at 80. The really step hill I pulled at 17k with lower gear my truck had drop down to 3th gear and with the rpm I was doing 40 to 43mph with the 3.42 same hill 3th gear was able to do 50 to 53mph same rpm. The lower greats do help get off the line but highway speed sucks. So far I'm happy with 3.73. And go with toyo 35 at2 be better cause they are little smaller the 35mt. But I still want find better tuner to change shift point when tow haul mode not happy with hardway performance on tranny tune.

Monster RAM ya was up and down think went to low with 35s with 4.30. The 4.10 I would say good with 37s and 35s with 3.73 so far can't wait to pull my trailer and 33s is about stock 3.42. Just from what experience i had pulling. 4.10s in dually with stocks size tires do good with 32s.

Hey man I don’t plan on towing anything (maybe 5-6k pounds trailer one in a while) I have stock 3.42 and I wanted to get 35” tires on my 20r wheels for looks. Right now very little difference in power and mpg with 33”. Any idea how it will work with the 35” and 68ref tranny?

Yukon gears are the business.

saloan hemmert the gear seem to be good the fitment went just fine. The only issue got some gear noise around 50 mph like not accelerating and not full coast Pattern good and backlash good. So that's only issue so far.

Just want let you know I'm not happy with the gears cause chip front ring gear last weekend was little hard nit happy going take them out soon

@Div Dev I'm running AAM 3.73 gears

I have them now in a 4.56 running 37s and tuck is in the shop right now I took out 5 or 6 teeth in thring gear on the front I will not buy again

@@CWBxASSASSIN are you talking about nitro gears or aam? Cause I broke couple tooth in front when I had nitro 4.30 gears I hated them and they where noisy. So that's why I went with factory gears Sam that what was stock in the rams and duramax the the 3.73 gears I have in my truck where out of duramax. If you watch my videos later I said why I did not like nitro

Justin P used to shift 60 mph in 6th now it's shifting above 50 mph

Last week end I finally did true test on my truck not happy could not pull the hill in forth gear ended up pulling in third at 45 mph normally pull same hill with 3.42 third 50 to 55 mph

Larry Gaspar Wow I’m surprised. I’d think you’d prefer the lower ratio for heavy towing. I know mine are great unloaded, but they suck for towing.

Ya better take off but in higher not to happy so might try 3.73 but me closer to stock with the 35s

Larry Gaspar Gotcha. Man for me the perfect ratio was 4.56 with 37’s but I towed heavy and a lot. I bet 4.11’s with 35’s would be perfect for what you want. Or 3.73 with 33’s.

Jim Cash. So far still good. No issues except the recalls. I don't abuse it don't tow in 6th. Just fished installing 4.30 gear ratio what difference in more get up and go from the 3.42. Still trying figure out on tire size. Only down fall is shift points with current tuner. Spoke with another might swith to anarchy tune do to the longer shift points when I tow

Hey thanks for reply , Im not looking to hit NASCAR , just have a good tuned & running diesel, and a lasting one. I intend to keep my truck till the RIP days come. I will be traveling touring the country very soon. Been looking at this Ezlynk tuner setup. was thinking on MM3,and Double R diesel tunes. But with this ezlynk its a faster update via internet connection anywheres. I also have 3;42 gets,I want them for the MPG . Well ya have to post more videos man. haha, Thanks keep her running .

3Gunner So far still good. Wish they can hold 3rd longer. Want to get some 4.11 gear in it one day. With some 35s

3Gunner so far been holding up fine when my trailer fully load with my rzr it's weighing about 17k total about 26k air bags helps at the rear only 30 psi in them also I have it tune with efi that's been good only keeping it 40 hp tune keep egts low

Larry Gaspar awesome sounds great , what exhaust do you have in there sounds good not loud in cab which the wife wants
