DT44 Stealth Turbo Long-Term Review

[@ryanlogan2911]

I had my DT44 installed in Wyoming. I then drove to New Mexico thru the Colorado Rockies loaded with tools & oilfield gear on Motorops tune 3. Elevations up to 10,000 feet and it absolutely screamed my wife commented I was passing everything on the road.

[@HunterSkiff]

That’s what I like to hear!

[@TheRandalHandle]

I will be getting one of these if and when the stock turbo gives up the ghost. I have also noticed quite a bit of S&B noise on my truck as well. Thanks for the good video.

[@HunterSkiff]

Thank you for the support! It is definitely a fun upgrade, really improves the driving experience. Not sure I could wait until my stock turbo failed to upgrade ;-)

[@kenbing8]

Just ordered the whole works, even the s+b intake! Can’t wait to install and get a gauge so i can look at everything

[@HunterSkiff]

Very nice! It really is a fun setup. Good luck with the install and report back once you get everything up and running

[@kenbing8]

@@HunterSkiff Will do! Chris over there even got numbers for stock tires and gears vs my eventual 35s and 4.56s so that they can give me parameters for both. Great customer service so far, on day one!

[@HunterSkiff]

Love to hear when people have good experiences with them. Their customer service has always been top notch for me. @@kenbing8

[@kenbing8]

@@HunterSkiffremoval and install went pretty well but god damn it’s tight in there! I keep getting (and then having to clear with Spade tuner) code P003A “turbo boost control position not learned” and each time I get it again the dash tells me I have 175 miles to go before limp mode. Have you heard of this? I know they don’t really want you to mess with the new actuator rod, but it is adjustable, soooo……

[@HunterSkiff]

Yea it sounds like the rod length is either too short or too long. There may even be a position relearn procedure for it. Best to reach out to customer service monday. Ask for Sean Lynn over there, he had a 2.8@@kenbing8

[@Duken4evr29]

Nice report. Big bonus, the DT44 has thicker vanes on the intake side, so they won't bend like the stock ones can in cold climates. Per DT, the stock turbo vanes are the thinnest they have ever seen, and the 44 can run on the stock tune if one does not want to tune. The DT44 upgrade is a no brainer if the OEM turbo gets damaged.

[@HunterSkiff]

Bingo! If I was stuck with a failed stock turbo I would definitely NOT replace it with another stock unit, especially if you think you’ll want more power in the future

[@coltonrumsey6529]

Please make more videos of this truck, going over reliability and stuff like that and some more sound clips Maby. I’m looking to get one of these and just really want someone’s personal experience’s

[@HunterSkiff]

Will do! Also, reach out to me on one of the many 2.8 related Facebook pages and id be more than happy to elaborate on my experiences with this turbo

[@sam5038]

I Installed the DT44/Map sensor with my tunable switch and stock air cleaner/ exhaust. My Colorado Trail Boss is so much better. I love the power now. It was difficult to install, but well worth it.

[@HunterSkiff]

yea buddy! that's what I like to hear. It's like a whole new truck again. Smooth sailing from here on out. Enjoy!

[@GSXRSIXER05]

About to pick up Duramax Colorado next week new diesels in the truck altogether would really like to go ahead and do a delete out the gate from getting the truck and tune looking for some directions on where to go for exhaust and tuning

[@codyt4019]

Cool video!! I would suggest getting an MBRP resonator. Helps with drone and raspy sound. Not to mention you can hear your turbo a lot more!

[@HunterSkiff]

Noted!

@@HunterSkiffyeah man not far at all, whoever had mine before me did some work, it's deleted and I found a 4 position switch under the dash, idk if it's hooked up or not but it feels like it is. One thing I'm looking to solve is that damn hpfp ticking sound. Annoying as all hell.

[@HunterSkiff]

@@tomsawyer118 best advice would be to delete the pump. What configuration is your truck? crew cab, extended cab etc? and what color? just so if I run into you driving around town

[@peterberglund5492]

Yup I added one to my 2017. I have also added snow water methanol injection. My temp's got a little higher until I added the water methanol, I also run 33" tires and 4.10 gears. Great info

[@HunterSkiff]

Good stuff!

Thanks YOU for the support! Glad you got some value from this

[@Section501K]

@@HunterSkiff I watched your and Duramax Tuner's videos before buying my DT44. I installed it a week ago bc my stock turbo was failing. I just towed a '65 Lincoln for IL to NC (no tune/MAP). What forums/FB/groups have good info?

[@HunterSkiff]

Theres a couple of them with "2.8 Duramax LWN Owners" and "Diesel Chevy Colorado and GMC Canyon 2.8 LWN Duramax" being the most popular. You have plans to install MAP sensor and tune? It's a whole different truck

[@Section501K]

@@HunterSkiff I have the Duramax Spade, 4 tune switch and MAP but the movers packed it before I could install it. Any tips on install? (New video idea? Haha)

[@HunterSkiff]

Youre off to a great start with the spade. The sensor is plug and play however you need an inverted torx to remove the sensor and install. Reference the CP/DT DT44 unboxing video for the specific one.

[@zacharywilliams4724]

I just deleted my 2.8 and want to get the most out of the dt44 when I get it! Who did your tuning?

[@anymouse6202]

Thanks

[@PHLTHS]

Out of curiosity, have you had any experience with the Garrett upgraded turbo to compare?

[@HunterSkiff]

No but the Garrett powermax is a compressor only upgrade turbocharger. It’s also very surge prone

[@PHLTHS]

@@HunterSkiff yeah I heard the same thing from LWN Racing. I'm thinking I should go with the DT44 instead.

[@HunterSkiff]

@@PHLTHS agreed. The Dt44 is better balanced in terms of having a matching upgraded turbine and larger vane assembly to lower drive pressure at high load. The powermax has neither. Dt44 has higher peak power potential too. The DT44 also doesn't have an issue with surge, regardless of what tune you're running, be it factory OEM file, stock turbo tune, DT44 specific tune etc

[@dixiemudtoy]

Dale yeah brother! I feel like it spools faster than the stock unit, but it's been so long since I've ran a stock unit maybe I can't remember lol

[@HunterSkiff]

Hahahahaha same. I don’t ever want to drive stock again!

[@adventurekidz1781]

Did you receive P003A code after install

[@HunterSkiff]

No?

[@crchrdsn]

Does this turbo require other upgrades to the engine or transmission? I also assume this will be emissions friendly?

[@HunterSkiff]

You are correct, this turbo charger works with the factory emissions equipment. It will work with a totally factory truck. Of course the real benefit comes from having the truck tuned. Nothing is needed on the trans side other than your regular general maintenance.

[@tjrob3452]

Great review. I still haven't gotten mine installed. I may bite the bullet and try myself.

[@HunterSkiff]

If you’re somewhat mechanically inclined you can do it. Some bolts are just awkward/uncomfortable to get to, but nothing complicated

@@HunterSkiff I'm going to try it next weekend, I will say that heatshield was a pain in the a$$ to get out. I took it out this weekend to start spraying the EM nuts/studs all week to get them ready.

[@HunterSkiff]

Good thinking with spraying the bolts ahead of time. It’s funny you say that, I thought the heat shield was a total pain in the ass, even after you get that bitch of a rear bolt out, the shield is a pain to wiggle out. I assure you the hardest part is behind you. Just take your time. Reach out to me on Facebook or Instagram if you get stuck or have any questions during your install. Good luck

Great job!!!

Thank you!

[@xxkaiserxx2505]

How much Hp Add bro?

[@HunterSkiff]

typically around 270-280 wheel HP. turbo can be pushed closer to that 300whp mark if you're so inclined

[@n1d0n]

I've had mine for almost a year now but I'm wondering if you noticed or if other people noticed that the tuning is smoky.. I'm pretty sure I had the same tuning as you. like full throttle tune 2-3 it's a bit more than a haze and when it shifts it's black.. I always had good tuning before that truck and none of my other truck smoked so I don't like that.. I did check for boost leaks and at this point I can't find any but the gauge is still going down slowly.. I think it's normal ? anyway other people with dt44 is it smoking?

[@HunterSkiff]

has it always been smokey, or has it gotten progressively worse over time? We don't have the same tuner, my files are smokeless

[@n1d0n]

@@HunterSkiff thanks for the reply, :-) yeah I saw below in the comments and we do have the same tuner... it's less smokey now as I did have 1 leak at the beginning. like I said if I did a boost leak test I can't hear any air anymore but I can feel the air coming out of my pcv.. the only other weird thing I have is I still have my stock downpipe - I just removed the DPF - but again other people did that and they don't seem to have issues and if it would be an issue I don't think that smoke would be the problem.

Added afe charge pipes, seems to spool up faster than before. Do you still have the exhaust manifold that you used to put the Garrett turbo on? Do you know if they still are making it? Thanks and have a fantastic day,

[@HunterSkiff]

Good notes on the AFE charge pipes. Might give their driver side pipe a try at some point. Are you referring to the factory Garrett turbo and the factory exhaust manifold??

[@peterberglund5492]

I thought you had gotten a after market exhaust manifold for the t3 you installed

[@HunterSkiff]

Oh. Yes. To install the custom holset turbo. Sorry I got confused when you said Garret turbo. The manifold is still available yes
