Incredible content and value to those of us that haven’t tried all this stuff. Hats off to you ,Sir.

Thanks for taking the time to do all this testing and sharing.

I just ordered my high country with the 3.0 and blue interior this week and I am very excited thank you so much for all the info it is very much appreciated 🤗

Haven’t had my truck very long but love doing mods and hoping companies support the 3.0 like they do the big diesels. Great info video man👍🏼

Thanks for the time and effort man. Really appreciate hearing your take and knowledge on this stuff 🍻

Thank you for all the information you provide.

I've been a fan and supporter of your page since I purchased my 2021 AT4 LM2 and began researching the trucks. About a year and a half ago, I bought mine with 50,000 miles on it. Since then, I've installed the PPE intercooler-your installation video was incredibly helpful, especially because I only received half of the instruction manual. I've also added PPE oil/tranny/diff pans and the intake pipe, among some other minor add-ons like Bilstein 5100s and RC control arms, which help fit the Nitto Recon 295 60 20 tires with minimal rubbing at full tilt, for those who might be curious. I'm sharing all this because I owe much of it to you and your informative videos. Thanks to your guidance, I feel much more confident in my truck's longevity, so again, thank you. However, I'm currently on the lookout for a PPE catch can, but I stumbled upon a VSE one instead. Do you have any insights on it?

Prouda you. I'm stoked on the PPE oil catch can/seperator. As an aftermarket automotive engineer, PPE's work is fantastic. If I had unlimited pockets I'd purchase everything they make lol

Stillen Air Scoop didn't make the cut? Great content Brotha! Keep up the great work!

Love your channel the best by far for all information for the newer LZ0! I'VE followed you install parts great install videos as well, but I put intercooler, S&B cold air intake big change with both of them I really never run over 200 degrees

I had issues with K&N, very helpful with the refund process.

These long format deep dives are really nice. I'd love to see a breakdown of some common issues you've seen or heard of with both generations of these engines

This was very kind of you. Banks just needs to get the derringer DONE ALREADY! I love duramax tuners and had one on my lml. over 500 horses for $700. He wants $3k for 40 on the lzo/lm2...NO THANK YOU! Hard to find gem: If you are looking to level your at4x truck and throw 35's on it, PEAK makes everything you need specifically for the Multimatic DSSV's! CMOM BANKS, give us a tune!!

This video is amazing keep them up on the 3.0

I am about to start shopping for a diesel pickup.l, most likely a lower mileage LML and/or a 3.0 Duramax. Either way, my goal is longevity, so to do get there, I am making my truck more durable, dependable and improve drivability. This video is very insightful with great content in that the 3.0 Duramax engines (LM2/LZ0) seems to take backseat to it's bigger brothers, the 6.6 Duramax Engines, in terms of tuning, aftermarket solutions and mods. It appears that the 3.0, just like the other Duramax engines, have untapped potential. This video may definitely influence my choice of a future purchase. Thanks for work put forth for this video and its content.

Thanks for taking the time to tell us about all of these mods. It is greatly appreciated. I am thinking about some of these items for my ZR2. I am your neighbor and would like to sit down for a minute and see what you think the best bang for the buck is. Thanks again.

Excellent video thank you 😊

great info! I think you should head to Canada and find the guys doing the DEF/DPF/EGR deletes and do a review :)

I have a CTS3 and have been running it for a while, I also had one on a 2002 7.3 SD for about 2 years. I loved it on the 7.3, not in love with it on my 3.0. I seem to have issues with it freezing and not waking up on startup. Probably 50% of starts I have to wake it up manually and every once in a while, it goes right back to sleep. It’ll freeze up about once a month and I have to disconnect and reconnect it, sometimes upwards of 8-10 times to get it to work correctly. I have it completely up to date with their update software. Otherwise, I like the mount and display, I run the 9 parameter display primarily to watch RPM, EOT, ECT, gear/TCL, TFT, Regen status, IAT, EGT and one more I can’t remember. and the 4 parameter display to watch regen. If I was to do it again, I’d run 2 banks gauges and will probably swap eventually.

I borrowed my brothers cts3 unit (he’s very happy with it on his Cummins), and it is glitchy, but works on my lm2. I’ve had more issues with it as it’s gotten colder for some reason. I like the data options though , and the big screen works better for my blind self than a banks

I did not know about green diesel tuners until now. I r been following EOC closely for a while now. My warranty is almost up.

Whelp! As you know I snagged a truck and was instantly drawn to PPE. Looking forward to crafting content and also sharing my findings. Great stuff here.

Nice video, I'm excited about the catch can coming out, do you have a timeline on that?

Appreciate your wisdom. Unfortunately I’m under warranty til 150k miles, so all my Modifications will be the kind that the warranty approves of 😂

Incredibly informative video, thank you for posting. I will research other videos you have posted. I’m purchasing my first 3.0 LZ0 diesel (23 with 18k miles) and would like to add some horsepower and sound. With so many different options you so generously shared, spending anywhere from $179 for some adds to $2000, What are your favorite two or three options I can install and not spend more then $2500. Once again Thank You for sharing your experience and knowledge!!!

Like watching all of your videos! I recently purchased a LZ0 diesel and trying to pinch the pennies where I can. What upgrades/changes would you recommend to maximize fuel economy? I don't tow hardly at all, just a daily driver.

What oil additive if any do you run? Also, what fuel additive do you recommend? I usef seafoam both in the oil and in my fuel in my 2.8 until I discovered diesel klean. Up until it was totaled I still used seafoam in the oil at least, but I would think there'd be something better specifically for diesel?

Purchasing a 2021 Sierra 3.0. really want to get tuning done immediately, and I really like the VSE kit with the turbo upgrade, unfortunately my wallet's not going to be able to take that for a little while. I think if I remember right it was somewhere around $2,700 I believe for their three tune with everything included (not intake). I looked at Duramax tuners and after the TCM refund it's right around 1500 bucks. thoughts?

Love the summary! Great work! As usual, wish us SUV (Tahoe, Yukon) LM2 owners had as many options as the pickups. Understandably so, the SUVs aren't as sold in the high volumes as the trucks. Random question. Does the STILLEN scoop/intake help anything? Do you happen to know if it fits the SUVs as well as the pickups?

So i have a 21 im leaning to the zilla pipe. Seems like you dont have a true preference for drop in filter. Said afe is thicker, would that be your recommendation? I know the drop in filter isnt going to change much, but whats your best pair to go with the zilla ppe pipe? Thanks for all your info!

Wondering if you’ve seen runvse’s new ccv catch can coming out in April? And if it’s what you’ve had in mind for one the times you’ve talked about it?

I've got a 2020 LM2 with 107K miles. Aside from a few sensor problems it's been a good engine. do you know of any high mileage problems that might come up?

Hi, I really like the detail you get into on your channel for this engine. I have a 2023 with the 3.0 LZO and it is my first diesel truck and I am very impressed with it. That being said I have a question regard oil temp, by the way I have had the Banks Super Gauge and it is probably the best add I have applied so far. Anyway my question pertains to what you said about oil temp and when it approaches 280 degrees. If I am on the highway my engine hovers around 230 or so and that to me is dangerously close to that limit you set of 280 before oil starts breaking down. I want to start pulling a camper trailer and I know that will add load and temp to the engine. What is a good oil cooler to install and where? Same question for the trans cooler. I look forward to you response. Thanks again for doing what you do here for this subject.

Has this engine ( more so the first version since its been out longer ) had issues start to show up with the injector pump failing. The reason I ask, I now am hearing that the HP4 pumps on the 6.6 are showing up some failures as in steel going through the system and the huge expense involved with replacing the fuel system although I don't think as bad as what the CP4 on the GM with no electric assist pump was.

Just bought my first lz0. Been watching a lot of your videos and I’m about start buying stuff to get more intake noise. What’s the #1 set up for it that you recommend? From what I put together it would be the factory air box with a new filter and the zilla intake pipe

5 STARS FROM ME FOR ALL YOUR LZ0 INFOR

Hey I just got a p249c code on my 3.0 do you know what could cause it?

Quick question. I performed a transmission service on my 2021 Chevy 3.0 LM2. I purchased a new transmission pan gasket. I torque everything to specs but seems a little oil is dripping from the pilot hole for the gasket. Could that be residual oil from putting the pan up and the new gasket? It’s shifting great and I don’t see any oil coming from anywhere else

🔥🔥🔥🔥🔥🔥

Is Fuely the name of the app you use to track fuel mileage and shows all of your prior fill-ups? I get a lot of results when I search on that. Thanks

you forgot a filter. AEM has a dry flow one out for these too...

Thinking of doing the PPE Exhaust on my 2020 Sierra. Do you think it would be any benefit for towing?

Of all of the mods, which helped the MPG and HP the most? EGT temps?

I'm new to this, how would these mods affect warranty

@DemonWorks what do you recommend if I just wanna get more turbo whistle out of the truck?

Well, it looks like the Banks Derringer for the LM2 / LZ0 is dead. The L5P is out and Banks removed all reference to the Derringer for the 3.0 Duramax from their website. I have been waiting so long but now I guess I need to look at the Edge EZX. Have you heard anything out of Banks that might make me want to wait?

My Chevy dealer says I need to use GM DEF fluid in my truck??? 2022 Chevy Silverado 3.0 . 68000 miles and the engine light comes on .replaced the DEF injector. dealer rejen twice

No info on the PPE transmission thermal bypass valve. What are your thoughts? Does it get tranny fluid TOO cold?

Any plans to try the Edge EZX?

If you have a $1000k to spend on mods. What would it be?

Chapters would have been perfect for this video

@demonworks does the S&B work on the ‘24 LZO? I assume it would be the same…

Any DPF/DEF delete mods

If anyone is interested in ppf carbon intake pipe and resonator delete pipe let me know. Barely used

There’s just so many different opinions on catch cans out there with no real studies. I’d like to see 2 different engines torn down after 30K to see if it really works

Welp. Ill be another 10 grand deep 😅
