Tuned 2.8L Duramax - POWER & ECONOMY

[@billm7164]

Gents, just an update. I have a 16' Colorado Z71 that I ordered. I now have 73,000 miles and I put about 90 miles a day on it. I put the Duramaxtuner in it after they released it and have not had any problems with anything related to the tuner. Had 2 NOX sensors go bad and a DEF pump replaced. Other than that.. GM has a solid winner! I say its better than advertised! I average 32.2 mpg each day. Its all highway but I cannot complain. Since I put in the tuner I have only used sport(#3) and performance(#4) on a occasion. It's a true match.. GREAT JOB DURAMAXTUNER!

[@samuelyeet6006]

How's is it holding up now, wait so did you not do a full delete and tune? Usually the delete means no more def right?

[@endutubecensorship]

Does the belt driven oil pump scare you? Its whats keeping me from getting one

[@ArgFarg]

@@endutubecensorship It's gear-driven on the 2.8. The 3.0 has the belt-driven oil pump on the back of the engine. The 2.8 has a timing belt though, easy to do with basic hand tools since it's on the front.

[@ryanlogan2911]

Recommend the CX racing intercooler. Any towing with a tune will melt the stock plastic end tank intercooler. - DT44 turbo - CX racing intercooler -Revmax torque converter -Flopro exhaust & Motorops tuned with the sly wink of Duramax tuner. 4 bar map sensor

Thanks for the helpful tip! @ryanlogan2911

[@Racecardriverrr]

How much HP and TQ with this setup?

[@jasoncarpp7742]

I agree. Not everyone needs the horsepower or torque of a large displacement diesel engine. Sometimes a small displacement diesel can do just fine for smaller loads.

What's the mpg?

[@rogerthieling8457]

My so far stock engine 2019 3500 with 2.8 Duramax Savanna Van outfitted with 1 ton Quigley 4X4 and raised roof Explorer package gets 21 MPG at 73 MPH with the 8 speed Allison. 1800 RPM at 73. Pulling 6,000 lbs of low resistance load in my open car hauler we averaged 14.8 going from Duluth, MN to Spokane, WA at freeway speed with a headwind. Coming back we averaged 16.6 for the same trip with a tail wind. 23,000 miles and loving the 2.8 thus far. Time will tell how it works out.

[@rogerthieling8457]

There was no mention of the fuel economy on the econ-sport mode. I know folks are getting about 30 mpg without a tune... what MPG could a person expect to see with the tune? I know it varies per driver, but I tend to try and maximize my economy (that game we play with the computer to beat yesterday's score) and want to know a ball park number regarding economy. Thanks.

I agree. Diesel may not be for everyone, but I believe that those who need one, or want one, should be allowed that option. I'd prefer mine stock, but everyone is different. :)

[@Duramaxtuner]

Thanks for the comment. Let's see what we can do.

[@jasoncarpp7742]

I've never understood why more light duty trucks aren't being offered with small displacement (2.0-3.0 litre) diesel engines. You see plenty of larger, heavy duty pickup trucks with 6.5 litres or larger diesel engines, but not everyone either needs or wants such large truck with such large diesel engine.

[@Duramaxtuner]

In our podcast with a GM Duramax engineer (Diesel Performance Podcast) he describes a new small diesel coming out soon - called the Whisper Diesel - 1.8L. He also said it's really difficult to launch new engines in the US compared to international markets, like the Southeast Asia. So there's some development time required. He indicated smaller diesel engines will be developed over time. We also talked about urban versus over the road truck needs and how stop-and-go nature of urban markets is not best suited for diesel engines given the need to regen - or something like that.

[@jasoncarpp7742]

That'd be awesome! Say you have a VW Eurovan who's original engine was a 2.8 litre VR6 engine, but you want something that develops similar horsepower, but delivers more torque, and gets better fuel economy and relatively longer life. For years, if you wanted a Eurovan (Transporter) with a turbo diesel engine, you had to visit other countries. I don't mind visiting Europe, but that's unforgivable.

[@jacobblankenship5655]

Unless my reading is inaccurate, the little Duramax doesn't use def at all. Obviously if they quit making you feed exhaust gas to the intake the engine would do even better, but it's nice you wouldn't have the added cost of an after treatment system.

[@rapidrabbit898]

The 2.8 Duramax is a cousin to that 2.8 CRD. But the limiting factor on tuning these is the limitations of the transmission.

[@detenator890]

When you say lugging, Do you mean that the tune adjusts the shift points of the transmission or do you mean the extra hp will allow for the higher gear? If we had an option for a stick shift, this truck would be mine long ago.

[@Duramaxtuner]

The power will allow for a higher gear, the trans tuning does also help. However, the main function of TCM tuning is increased drive-ability and providing the ability to stretch your powerband.

[@TheLualgaro]

Can you tune a 2.5 diesel Duramax?

[@BigFrogs4x4]

How does this effect a dealer warranty? Also does it work with an EGR/DPF delete kit? That is the plan for our ZR2 Duramax once the factory warranty has expired.

[@Duramaxtuner]

Tuning may affect your warranty so it's a good idea to check with your dealer. Some dealers are cool - others are not. However, if you tune the truck under warranty and there's a catastrophic failure of the transmission or engine, then the manufacturer would investigate to see if the engine has been tuned. In that case, you're screwed, probably. We've also had issues when the dealer automatically updates the calibration. That usually disables the new tune and requires an update from us. Yes, these little trucks work deleted. But we do not offer delete tuning for them or any diesel truck - we only tune emissions equipped trucks.

[@randysretired2020]

No business is going to advertise supporting deleted vehicles. That’s an open invitation for the EPA to investigate and fine businesses, especially with Democrats in charge.

Any insight from the miles you've put on your test truck?

The truck in the video is an emissions equipped truck. In fact, we do not sell anything that defeats the emissions equipment. That said, your Colorado will love our tunes.

I currently own an OBS 7.3 I’ve done a little to it and use a TS chip, that’s old school and it works, but I’m skeptical about fooling around with a new generation engine it seems to me that a small displacement engine has been “optimized” enough by the factory and keeping the reliability factor on track, I’d be afraid of high exhaust temps and higher temps on oil and transmission as well.

[@Duramaxtuner]

Thanks for your note Powder River. We've done countless hours of road and dyno testing of our calibrations while monitoring engine gas temperatures and other parameters without any problem whatsoever. We've sold these calibrations to hundreds of customers who tell us they're very happy. Our calibrations add horsepower, yes. But they improve on what the factory already achieved. For example, our tunes improve on the dead pedal - that mushy, slow throttle response that makes low-speed maneuvering a pain (especially with a trailer). Speaking of trailers, if you're hauling GVW on an incline, the calibrations allow you to maintain speed and even pass if necessary. The 2.8L is not a new generation engine - it's been around for more than a decade and sold in Asia. Plus, our calibrations are sold with the emissions equipment intact without any negative effects on regen frequency.

[@powderriver2424]

Duramaxtuner thanks for the kind reply, that’s an interesting note, I’ve often wondered if manufacturers would use engine platforms they’ve developed for other markets.

[@Duramaxtuner]

Having the room to install a Duramax 2.8L and its related transmission may be one thing - but ensuring the engine harness (wiring) and all the accessories work is another. You could do the swap but then add gauges or whatever to monitor the various diesel stuff like regen but it won't look factory. That wiring stuff is a deal breaker for some swaps - not impossible - just very, very time consuming and if there's a problem you could be stuck for weeks.

[@Ps-uv2kx]

Thanks for the reply...I do not mind the pickup not looking factory, I have no intention to sell it. If the wiring for the speedometer and rpms ect is not to strenuous, I have no problem mounting gauges for the diesel side.

When you ask if this "could go into a full size 1500" - you're asking if the tune could go into the larger, gas-powered truck? No this is a tune designed for a diesel engine, so there's no compatibility whatsoever. DT's 2.8L improve the dead pedal, which is the gutless response you may be referring to.

My apologizes.. in your opinion could that diesel engine go into full size say 2012 GMC Sierra 1500 and work out? 90% of the time a simple daily diver and then load kids in there for practice or games. I throw sports equipment in the back for the most part.

[@Duramaxtuner]

My apologies to you - just never thought of that before. Crate 2.8L engines are readily available through the manufacturer - so yes, I'm pretty sure you could drop one of these into a 1500 style body - why not? You'd have to include a transmission in the conversion and no doubt modify the engine mounts and drive shaft. There will be other challenges, like wiring - but that stuff is a typical everyday challenge to a diesel tech. Will be expensive.

[@NetsarimTheWatchman]

I am very interested but I am not seeing where you showed your MPG increases or decreases with any specific tune. I was informed that nothing is going to increase MPG averages unless a full delete and removal of the exhaust system was done. I was told this by more than one 2.8L owners. Said anything that promises MPG increases without the full delete - removal of the EGR DFP and SCR and then removal of the hardware components is just snake oil. So I am still open minded and interested. I like facts not tales of over inflated MPG increases. What have you seen increase or decrease with your tuners in MPG specifically? I dont want to hear about horsepower and torque although those are important. I want your MPG data

[@Duramaxtuner]

@TravisSmith-hm4tt Members of our staff have personally seen a 2-3mpg increase on the highway after tuning their personal vehicles. While our recorded data on these statistics is lacking we do have a few facts that support the idea that tuning will increase your fuel economy. Firstly, we do more than just add fuel to increase efficiency when tuning. Improvements in timing, boost pressure, and the shape of your power and torque curves over the factory calibration to add efficiency without increasing fuel consumption. The improvement in efficacy from tuning can definitely help improve fuel economy if you drive in a fuel efficient manner. However, combining ECM tuning with TCM tuning is really where efficiency starts to become noticeable. The improvement to the power curve coupled with improved shift points can really maximize your fuel efficiency. Getting your truck moving at a steady pace and holding a higher gear instead of lugging your truck up to speed at a low RPMs/levels of power and holding the truck at a high RPM to maintain speed will definitely improve your fuel economy. And hey, don't take out word for it.Throw a post up on one of the 2.8L Duramax groups on FaceBook or one of the forums and see what our customers are saying!

@@Duramaxtuner I'm pulling a 5000 lb trailer behind my 2018 Coly (Coly weighs in at 6000 - loaded with 2 pax and gear in the bed)with the Switch on The Fly configuration and the TOW tune selected. Combined weight of the two vehicles is just at or about 11500 lbs. Frankly, I'm not impressed with the Tow selection. While traveling up with a gradient of @7% grade, I am at WOT (RPM's above 3K) and transmission temps over 230 by the time the summit (7 miles)is reached on a 68F day. I never see 6th gear (particularly in Auto mode) unless going down hill, or on a very level roadway and no wind conditions. And this is at sea level up to @ 1500' of elevation change. I shudder to think what would happen if the altitudes were above 5000' as in the Eastern Sierra range of Ca. It definitely has me limiting my options to travel with the trailer to mountainous areas. Even at the sea level height range I am only getting 13 - 14.7 mpg on average. To be fair, I also only get 22 - 23mpg at best with any of the tunes and not towing the trailer. Told that to another Coly owner (Baby D-Max as well) and his 4x4 Coly was getting 38- 33 MPG... Couldn't believe it. Out of the box mine never approached that kind of range. No better after being tuned with any of the tunes. It is more "fun" to drive with the a tune selected, but any performance gains seem rather elusive.

[@AnthonysOutdoors]

What kind of fuel economy can be expected with the tune and towing a max 2000 pound boat/trailer? Debating if the diesel is the way to go over a gasser?

[@Hazinclayton_007]

Im watching this because im going to swap one into a jeep comanche!

[@gabe22313]

That’s sick

[@adamdavis397]

Hi guys, I tried contacting you through your website and the captcha was malfunctioning and kept me from sending my inquiry. Do you have a dedicated email I can send to? Thanks!

[@Duramaxtuner]

Sorry about that. [e-mail] will always reach us.

[@Duramaxtuner]

Yo-u're email came through, but for some reason we cannot see your email address. It seems to have been sent from [e-mail] to [e-mail]. -Which we obviously have never seen before. Any chance you can give us a call? 815-568-7920

[@jasoncarpp7742]

I haven't seen any Duramax powered Chevy Colorado or even GMC Canyon. Nor have I seen the engine advertised for USA buyers. Can you think of any reasons for that? I'd buy a truck with the "Baby Duramax" 2.8 litre if it were available where I live, and if I were in the market for a small/mid-sized truck.

[@SuperLabonte43]

You may have to order one in through your dealer. I haven't seen many at all yet either. I know that my dealer in a town with only 5000 people is actually getting one in this week, and I think my dad is snatching it up lol.

[@jasoncarpp7742]

+blake woolam I know. I'd like to see more small displacement diesel engines sold here in the USA.

[@SuperLabonte43]

+Jason Carpp I agree. I belive there was a 4.5 isuzu that was supposed to go into a half ton Chevy, but it never happened. I wish it did.

[@jasoncarpp7742]

It's an unforgivable shame that never happened. I can imagine it going in the Chevy C/K1500, while the Duramax V8 would go in the 2500 and 3500.

[@SuperLabonte43]

Yeah, it would have made a lot of sense. And chevy would have beat dodge and nissan to the half ton diesel market

[@scottwitkowski1298]

If I buy a Canyon, I'll be new to the diesel world. Can I install your tune on my own? How hard is it? Very interested in getting in the diesel world but a 3/4 or 1 ton is overkill for my needs. The little Duramax seems like it will fit my needs but I would like to tune it if I pull the trigger.

[@gamesofcontent]

plug it in a push a button

[@cowlumbus]

I’ll keep my Touareg 3.0 Tdi and box trailer when I need to haul little things. In the mean time I can tow my 27ft RV and 7000lb boat no problem and still fit in a garage unlike my F150.

[@gerardm.5047]

why do you hate America?

[@bradhaines3142]

could you do the 'sport' tune and be able to sustain towing if you upgrade the radiator?

[@Trenscendent]

Lmao go back to school

[@Duramaxtuner]

The radiator would not need to be upgraded to run the Sport Tune.

[@MrDjh66]

Was a grand

[@howardmiller4241]

Will this tune void the factory warranty ?

[@Duramaxtuner]

It depends on your dealer. Some dealers are cool - others are not so cool. When you buy tunes from us, we include a stock tune so you can reflash your truck back to stock if necessary.

[@rockriver15]

Who cares about factory warranty

[@nolanmitchell7319]

Hey is this the same block that's in the 2005-6 Jeep Liberty's with the diesel

[@Taznar]

okay now when are we gonna see these things cranked to 400hp+

[@johnstevens7643]

If your getting 7-8 mpg towing out of a full size with any diesel you have problems 😂

[@genejackson4261]

John Stevens I get 7mpg but what do I know this kenworth 680 has a big engine

[@howandwhy...]

Our firetrucks get about 5 if we're lucky lol

[@brucefredrickson9677]

Too bad the GM 6L50 transmission is the weakest link here. It's a car transmission that regardless of tunes is still a car transmission. GM has better options but went cheap where/when it really counts...such a shame.

[@nilknarf1596]

if theres a better tune then why is the factory not doing it ?

[@stuartpickles6907]

Nilk Narf because of EPA regulations on manufacturers

[@nilknarf1596]

wrong, correct answer would be that "better' is a subjective term... the epa sees those that limit emissions as "better" while a petrol head sess the best performance as "better"..... twat

annnnndd theyre canceling the 4 cyl duramax come next generation

[@eric38acp]

I would hope that if I just traded 30+K greenstamps for a truck, it would not need a power boost. Just keep the keys. I'll keep my greenstamps

[@tysonjez]

it doesn't need a power boost... it's just an option for those that want. it's like kids that turbo their civics. they didn't have to do it. some people just like the freedom to modify

[@Icutmetal]

Eric Williams There’s a big difference between need and want, man.

[@camaro_kyle6851]

if i had one thing to tell chevy, it would be get your head outta your ass and build a NEW express van. like they had the same design since the early 2000s. ford and ram changes the design of theirs and it looks bigger and better. CHANGE IT NOW!

Until the oil cooler lines crack leaking out all the engine oil and seizing the engine. It's just another gutless piece of shit durrrrracrap.

[@Duramaxtuner]

So I guess you won't be driving a Duramax any time soon.

[@ap1237]

Duramaxtuner you couldn't pay me enough to drive anything with a GM badge on it...

[@Duramaxtuner]

Don't worry ap 123, we won't even try. Best of luck and thanks for reaching out.

[@ap1237]

Duramaxtuner wasn't reaching out. Just stating some facts. Looks like I got under your skin in the process. Take care now.

[@ProbeGT2]

Duramaxtuner That's some serious P.R. Skillz hahaha keep calm and try not to feed the troll.

[@TheBlueCollarPreacher]

The real truck is the Red 1st Gen Dodge behind ya'll

[@Duramaxtuner]

Yes sir - remember that project well. Very happy customer.

[@dylanipes5782]

The Blue Collar Preacher is that why they got to pull that piece of shit around?

[@hotsauce3700]

Fastest way to void your warranty and for good reason. Also, there is no info on fuel mileage and emission compliance. Oh well.

[@Duramaxtuner]

These calibrations are emission compliant.
