Tuned Colorado Diesel w/ Downpipe & Exhaust vs Stock Colorado ZR2 Duramax

Comparing a stock Chevy Colorado ZR2 Duramax to another tuned and straight piped (with downpipe) Chevrolet Colorado Diesel!! Big gains with HP, Torque, and MPGs (not to mention the sound and turbo noises!) 500 likes and I'll hoodstack it (for testing purposes of course).
Weekly videos featuring my 2018 Colorado ZR2 Diesel, 2003 Chevy Silverado ZF6 LB7 Duramax, and 1994 BMW 325is E36 LS1 T56 swap, and friend's videos.

Years ago Chrysler was putting this into their Dodge Caravans overseas and I saw a test done on a 1998 with a 2.4 L version of the same engine and it got over 50 miles per gallon with a single person in it and went 1050 miles. Then they filled it up with seven people filled up the fuel tank and it went over 730 miles with the same 20 gallons of fuel with seven people in it.

I heard some reporting 36 mpg but they are probably in the country doing long commutes with no traffic

The Silverado 1500 diesel gets better fuel mileage than the Colorado diesel. I want both!

[@digdug9639]

Just a heads up about the Chevy 2.8 Duramax. There are no gauges for the turbo at all. Even more annoying is nothing to monitor particulate filter or do a manual regen. Usually there is no notification that it is doing one. Apparently you are suppose to be able to hear the difference, but I can't. I've had my truck in 6 times in 3 years for sensor replacement and manual regen. You can get a device called Autel 808 which is a scanning tool, but also allows you to monitor soot filter, time since last regen and most importantly you can do the manual regen yourself if need be. They cost a bit less than $500.00 but well worth the money. Chevy could have included more to monitor critical systems. other than that I have had no problems with my truck.

[@jasoncarpp7742]

I'm not a fan of where the gear selector is. I've always preferred the selector being up on the steering column, like most trucks of 30+ years ago.

[@digdug9639]

I have a 2017 and the only thing I have in it is a Stealth chip I had one trip that actually hit 42.0 miles per gallon. Though not as impressed with the performance otherwise. Also, haven't hit that 42 since, so not going to attribute it to the chip, as it could have been a fluke. Looking to do a full tune soon. Have also heard some good things about Pedal Commander to get rid of dead pedal syndrome. We'll see what the full tune does first.

[@matt13ross]

I wouldn’t do a pedal commander if you’re getting a tune. The tune will take care of the dead pedal.

I don't own one of these, but I test drove a stock Duramax and a V6 Tacoma since I'm thinking about getting a mid-size truck. The Duramax was a little more responsive than the Tacoma in my drives. Just an FYI, since you said it was the slowest truck in its class.

You need to get a big intercooler that will make the biggest difference Mine is producing 151 kW @ 3600rpm and 580 Newton metres of torque at the wheels And this is done with a chip and a Tune straight pipe snorkel big intercooler and K&N filter♠️♦️

[@matt13ross]

I thought about an intercooler, but probably after a turbo upgrade.

Yea that’s fine

so what is the tune for it

[@matt13ross]

HD diesel

[@nathanyoung3158]

ok thanks i plan on getting that next year then for my diesel zr2 i got about 75000 miles on it now just have had for a year and its my daily driver

[@matt13ross]

@@nathanyoung3158 I’ve had mine about 2 years

[@nathanyoung3158]

nice i have 50000 in one year so next year i will have to do the timing belt and the tuner too hopefully at once should be fun

[@robm3357]

It’s a good little motor but don’t go crazy with the tunes. I see a lot of these blowing up. I believe they are running close to max with a stock tune. Remember it’s only 2.8 litres. If you run it hard with a high output tune ....... Good luck on life expectancy......

[@matt13ross]

Yea I’ve read of some stories. This is a general mild tune, 49hp 70tq.

[@tomaskennedy1936]

That is a isuzu japan engine?

[@matt13ross]

Umm sure?

[@offcourseoverland]

Thailand

[@DCBuildingOfficial]

It's a VM diesel from Italy, designed in part by GM. GM bought part of the company from Penske then Fiat bought the other part. GM sold their part to Fiat and kept the design that is now being build at a new factory in Thailand. Jeep and Dodge ECO Diesels are also built by VM and share some parts.

[@jordancleal6380]

your best ever wasnt 29, that was just the best you achieved in those 50 miles. im sure youve done better without knowing also the tuned truck you averaged 30 and bested 35.

I live in California which makes me have smog checks on my ZR2 Diesel 🤬

[@Brvndon777]

Same, debating on doing a def delete or not

You're SOL then, lol

I don't live in Cali, but I don't see how anyone could really get away with that there.

Don’t worry we have illegal smog check in Cali and we pass fine if u have a vehicle that doesn’t pass cali emisiones and laws

I really really hope someone will come up with a delete for my LM2 , in the end you can’t live in Alberta and have an emission compliant diesel Lol

Not gonna happen, which sucks!

stock has a way better idle sound

Stock idle is silent lol

[@rock-uu7qr]

@@matt13ross Yea but its hard to tell when the microphone is right on it. I really like the the after market exhaust but that bubbly noise at idle sounds kinda strange

[@matt13ross]

I think you'd like it in person. Honestly my favorite part is the idle and low revs. High revs it doesn't sound great IMO.

[@rock-uu7qr]

Yea I wanted to buy the mini duramax but the only ones I can find are like 40 grand

Most are closer to 50K.

I have an eco diesel wrangler.............. makes more power stock than that ever will..... banks tuner and I get 30 mpg highway 18 in 4lo crawling...... and around 540 or so tq from the crank.. buddy of mine is trying to beat me with his baby duramax..... I hope he wins cause I like chevys but I really think it's a lost cause.....

[@matt13ross]

Right, the Wrangler has a larger newer V6, much more power than the I4 Duramax for sure.

[@jonyovanno4145]

Just put the Pedal Commander in and be done!

[@matt13ross]

That doesn't add any power.

[@astrocomical7159]

Diesel is too small as 4 cylinders. Need minimum of 6 cylinder. The truck has only baby diesel and it sounds like it too. Little baby sound.

It is a baby, and in a baby truck
