Stoked to see you guys working on this platform ‼️‼️‼️
Please start working on the LZO, I'm very interested in future tunings
Yeah, would love to see some work on the LZ0 as well!
Another great video! And nice Meyer Motors plate! That dealership is about 15 min from my house! 😁
Can't wait to see what you guys can do with this platform
Thanks, Hunter. We are having a blast like we do with every platform🤘
I currently drive a 2022 Silverado 3.0L LM2 Stock Engine with 11184 miles (18000kms) on it. The best highway fuel economy I have achieved is 34 mpg. (6.9L/100kms.) Cruise Control was set at 74.5 mph (120 km/h) for 226 miles (363 kms), with perfect driving conditions - no wind, 46.4F (8C). Geographically - Jasper AB (elevation 3465.83 feet to Edmonton AB (elevation 2198.16 feet). In my opinion, I'd say this is quite outstanding fuel economy for a stock full size truck. I have no doubt in my mind, that the LM2 is GM's best engine built in the last 10 years. I enjoyed your review, and hope you share more information/updates for the LM2!
Thanks for the personalized info. Be on the lookout for more info on our end too. We are digging the 3.0L LM2!
I love your reviews
This gives me hope for the future. Have been afraid to ditch my 2.8L because no one was able to tune the 3.0. Would love to see a 325hp/600tq out of this platform.
We love the 2.8L, but this is going to be good as well!
I’m in the market for a LZO ! June is the month I’m buying! Love what the 3.0 L has to offer . Looking for a max tow package . Can’t find any .
PPE makes an awesome intercooler for these 3.0s
Yup, following. As a Yukon LM2 owner (future) i need me this. Thumbs up and subscribed.
Awesome video!
Will your tune be available for the refresh trucks with the LM2 also? I know some of their PIDs are different.
So that low speed (1100) rattle was teh VGT rod. and the powertrain vibration could have been surge? is that even possible with this small of a unit?
Interesting video on the baby Duramax. I own a '23 Silverado 1500 RST with the LZ0. Very nice powertrain. Very smooth and quiet for a diesel with lots of torque and more than adequate horsepower for my needs. I get 16 mpg towing a 3500 lb travel trailer from Cali to Arizona and back (twice as good as the Frontier 4.0l V6 got) and get 28-30 mpg at highway speed. This truck drags the trailer up long/steep mountain passes at 65 mph with cruise control on effortlessly. The new baby Duramax does suck up lots of DEF while towing though.
Interesting. Thanks for that feedback!
My lz0 sucks the def without towing, my 2016 f550 uses less def and it tows all the time
without knowing driving habits, this is useless information. i'm yet through my first DEF refill at just under 5000 miles. @@juledoren
Awesome man
I have a LM2 Silverado. Best powertrain I've ever had... Love the thing. Hope you guys make a tune for these things. I know one is out already but its from companies I've never heard of.
We do have 3.0L tuning for the 2020-2021!

Great article, now fix the L5P and L5D
When can we see the new LZO?
@duramaxtuner you went over everything except the exhaust/discharge size. OD IS 3.75 correct? Do you know if it has a lip for the gt flanges or flat? Post a picture if you can, thanks
What blanket size would fit this?
per a powertrain engineer WATCH teh head bolts. it was a concern during development.
LM2 had LOW AND high pressure EGR. low being post DPF high being pre. high is used typically to warm it up and is used ALOT in cold climates (alaska)
Thanks for the heads up!
Looking into getting a Silverado with the new LZ0. Hopefully, you will get your hands on one. Would love to see what can be done with that one.
We are definitely looking at the LZO.
How much does it cost to have a tune like this done ? I have a 2021 with a s&b cold air intake, 6 inch lift with 22x33x12.50’s. Would love to have a little more torque and power.
What does that mean for LZ0? Really interested in seeing what can be done on top of what the manufacturer has already achieved.
Hopefully soon enough we will have access to that engine computer!
Yes! Finally! Will the tuning be available for escalade diesel also?
It's not on the list, but always possible.
Will there be an update to this video. I have the same car. Would really like to have it tuned and enjoy the 3.0 to its fullest
Possibly down the road. Thanks for the comment!
Thanks for the video and how the turbo works. I’m very new to diesel trucks and bought a 2022 3.0 elevation 11:49 Duramax. Every once in a while my truck has light white mist or smoke From exhaust for about a minute when driving off. Only done this a few times and dealer can not find anything wrong and unable to duplicate the smoke. Goes away for a month or so and then happens out of nowhere. Someone said maybe the turbo, oil, fuel or coolant? Dealer said all good but happened again today? Any thoughts. Thanks
There is plenty of reasons why it could be happening. We'd need the truck to get a concrete answer.
@@Duramaxtuner Thanks for the reply. I’m in SoCal. Has not done it again and dealer thinks it is nothing. Fingers crossed
Interested.
2021 GMC baby Max 6 inch lift and Nitto Grapplers.
I'll take max tune available 🙏
Give us a call, 815-568-7920!
Were can i buy this tune for. My lm2 been waiting on banks but they taking forever
We have tuning for the 2020-2021 3.0L. It's on our website duramaxtuner.com
I'm hoping the 2024 SUVs get the LZ0. Then I'm hoping you guys will have SUV/LZ0 tunes. Here's to hoping all the pieces fall into place...
Hopefully down the line!
Brand new owner of the LZ0, 260 miles, lol. Would definitely be interested in a tune. Would it be a plug in module or a ECM flash? I don’t want to lose my warranty. Subscribed.
It would be an ECM swap until a tuner can unlock without an ECM. Hopefully we get an LZ0 of our own soon.
how hard is this to do if we can not make the trip to your shop
@@Duramaxtuner
Great video!
1. Can we get this tune for our LM2? Where and how much?
2. For “off road use only” is deleting possible?
1. Yes. Already taking orders.
2. No deletes.
Where can we place orders?
@@Duramaxtuner why can’t anyone delete this truck???
@@dimestackwelding607good question, i guess they don’t want to go to jail for that nonsense.
@@nahbro3240 im in alberta, tons of deleted trucks. its not a matter of being scared, if you live in a place where you need emissions test to register your truck then you have to have it intact to be able to drive
I've always been a duramax guy and have owned a 05 LLY and a 2015 LML, Both were super reliable. I'd be curious to find out the reliability on these baby duramax's and see if they are as good as the HD trucks
We are digging ours thus far!
Do you have a rough idea when this tune will be available? Website I can keep checking for in stock/ready to ship? I NEED ONE! 20 Silverado Crew
Taking pre-orders now. Give us a call, 815-568-7920
any Idea when tunes will be available for all LM@ motors?
We currently have tuning for the 2020-2021. Check it out here: duramaxtuner.com/diesel-tuning/2-tune-pack-incl-tcm-tuning-unlock-your-ecm-credits-for-lm2-3-0-duramax-2020-2021.html
So when are you coming out with a obd tuner with profiles?
We'll see if someone can crack that nut.
Greetings, 21AT43LDRMX, how did you tune up to 288whp?
We use HP Tuners.
The turbo may look easy to get to, but getting the DOC off is a huge pain
True story. I may have overestimated the accessibility of the turbo. Ha
any updates/eta on refresh 22's?
Nothing yet. Trying to get our hands on an LZ0
What new mpg and new horse power & what can I buy for 2023 3.0 Diesel to improve HORSE Power & MPG
We see a 1-2 MPG bump given the truck is working properly and your driving manners are geared to trying to gain fuel economy.
@Duramaxtuner I understand completely the driver has everything to do with MPG thank you for information and update me on way to take next steps for Horse Power
How did the tune effect fuel mileage?
With fuel economy-minded driving habits, 1-2 MPG gain.
When are we going to hear some news about a new turbo upgrade for the LM2 ?
@jean-dominiquelaflamme5185 It's still in development. We have had so much tuning and turbo development this year it has been hard to get both the tuning and turbo for the LM2/LZO through our process together how we like to. Resources are freeing up though so we should see some progression in development soon. Keep an eye on our Facebook to stay the most up to date.
Yes sir will do for sur ! thanks a lot and keep up the amazing work you guys rock 🤘
Unfortunately I bought a 21 with 12 thousand km on it last year. Had nothing but problems gm warranty wasn't helping me tried multiple dealers they were trying to delay me until my bumper to bumper ran out. Got tired of driving dealer rentals. Traded it in for a 21 ford f250 when I realized nobody was going to help me haven't looked back.
Sorry to hear that.
So we r talkin 285/290hp to the rear wheels & 560ft/lbs of torque w/ this middle of the road tune!? That is awesome! Forget the LZ0 until there is a def delete cause stock it eats thru def so w/ a tune you will burn thru that 5 gallons in a tank of fuel! W/ that said, have you driven w/o your foot in it to see what kind of mpg you can get? Best I have is 34.4mpg w/ stock tuning, 4x4 SLT & 2” lift w/ 295/55/r20 tires
And that's hand calculated? On board computers tend to be optimistic! I've always had to have the dealer correct that under warranty (VW, Ford, and MB, all gas)...and Nissan dealer told me that it's supposed to be wrong lol!
Well your wrong, it does not eat thru DEF. A tank will last between 4000-5000 miles with normal driving. Hardly eating thru. Let’s stick with the facts shall we?
@@hammer-r mine does not get anywhere close to that and I will qualify as a mature driver, easy on the throttle with mostly hiway miles. 2500 miles for 2.5 gallons is what I'm figuring. My sons best friend's '23 is worse than my '22. Not sure how he drives but his truck has almost triple my mileage so more data.
@@denniswilliams2098 not sure what to make of your comment cause your calculation is in line with what I stated. I’m a mature easy going driver and yup about 5000 miles for a tank of def. But when I trailer like I have been, then it eats it much faster. But when I’m driving on the highway at 60 I’m getting about 40 mpg. So I can’t complain. My best 50 mile loop was 44.9 mpg. Best truck I’ve ever owned. But with everything, time will tell. But so far I love it. It’s a torque monster as I pull my 8000 rv up steep dirt roads camping.
I’ve heard different rumors about how the turbo on this motor is cooled. Is it oil cooled or cooled with coolant?
@jko0526 It's primarily cooled using engine coolant however the oil supply most likely provides some cooling as well. The placement and connection for the oil and coolant passages are quite interesting.
Thank you for the reply and the in depth video!
Why don't u have a BANKS gauge on it to monitor the regens? This way u can prove u aren't making it regen more then stock settings?
What is the difference between this turbo and the 23s Turbo?
Give it a year these trucks will make 1000hp
The progression of diesel!
Can you explain why you subtract 15 psi off the monitor to get the max boost psi?
Atmospheric pressure is around 14.7psi……. So it’s easier to say subtract 15 then 14.7
I have a difficult quetion for you: whats the point of tuning a diesel? It will never feel like a gas. I have a new ecodiesel and i love the driving dynamics of the stock engine. Enjoy rolling down the road. Diesels are for towing and driving relaxed, not for racing..
Tuning a diesel provides s horsepower increase, helps with issues such as dead pedal feel, helps with MPG, and can help with towing.
@@Duramaxtuner everything in physics is a tradeoff. It is impossible to believe that the engineers gave up on better fuel economy and more power if there is no cost to pay in terms of reliability. You are trading durability for performance, thats what you are doing, but that's not my point. My point is that if u increase the performance of the diesel so much that it feels like a gas motor on the road, they it wouldn't feel like a diesel and would lose all of the appeal of driving a diesel. When u get an electric car u have better performance, but u miss the sound and the behavior of the internal combustion engine, don't u? Its the same when trying to improve the performance of a stock diesel.. There is a charm in the way diesels run..
The new engine # is actually LZ0 now not LM2.
Yes sir.
lm2 is bascially same as LZ0 @@Duramaxtuner
sustained load EGT on stock tune was over 1400. so hearing yo say it ran rich makes a ton of sense.
the intercooler is easily overwhelmed and that electric coolant pump doesn't run 100% of teh time. they tried to keep IAT neat EGR temp was teh story i was told.
the original trans tuning (launch tuning) has it shift at 3900RPM 1-2 then lock the TCC. the updated trans calibration moved that up a bit and makes 2nd gear not preform as well (less time to make torque l5p style?) these were all WOT runs and experiences.
i have an "IKE" run on my channel with some (not this much) data maxed out at 15k combined. long video since its uncut.
TRANS tuning was my BIGGEST COMPLAINT! after updated calibration it became a DOG.
watch that converter clutch. mine started to fail as have others. updated calibration brought it in softer (less shock) but dmg was already done.
The 10sp is very picky in the mustang once u start adding power and tuning the trans, they don't like it. I'd assume this is a similar version of the Ford 10sp since they were both involved building it
@@kwmiked they are part for part the same. Ford vs GM 10 speeds on half ton
The recommended oil is junk. We have a couple of them in our fleet for work trucks they burn 5 qt of oil at the recommended oil intervals. Put 15w40 delo 400 Magically the oil consumption disappears doesn't even burn one qt of oil by the recommended oil change intervals and better MPG.
Don't go saying that it's gonna ruin the engine and the bearing and bearing clearance. They've been running strong no problems. Where it snows still good oil weight Any diesel engines a good idea to let it sit there and warm up.
Thinking about moving mine to 5w30 delvac esp, I wanted to go 5w40 turbo diesel but i thought itd be too thick. On the mobil 1 site alot of the diesel oils have basically the same specifications. On the 0w20 esp it says GMLicensed but have all the same specs as their 0w30 0w40 and 5w30 esp. Their all mid SAPS low ash low sulfer. The turbo diesel does have a API SL cert like a 0w20 esp but the delvac doesnt
I’m seeing SHITLOADS of 3.0’s on the road now. Products for this motor can’t come soon enough
Be on the lookout👀
ditch the emissions gear. burn the epa to the ground and let this baby dmax really perform and be efficient
I have already blocked the EGRs on mine and drives way better and hardly any turbo lag. I bet it knocked off two seconds on the 0-60 time.
23’ lzo diesel, I was surprised my oil at 400 miles was blacker than my 2002 duramax has ever been, all those extra gasses can’t be good for the engine.
@@jakesvideos8204 first oil change??? Wonder if it has anything to do with that 🤷♂️
@Jakes videos Just cause it's black doesn't mean it's bad. Only way to find that out is thru oil samples. 200k on my 6.7 Ford and it turns black as soon as u start it after oil change. It's done it since it was new. I go 8k on oil changes and sample every oil change. It gets analyzed at my Local CAT dealer since that have the Lab right there
Please stop with the stupid comments about emissions on these pages! U only make it harder on everyone the more STUPIT people like yourself bring this up on public pages for anyone to see
