2025 LZO Engine mods

[Gandalfthegrey]

Hey everyone! Recent owner of a 25 ZR2 diesel. Ill be updating my profile with pics and mods shortly, I just created this Profile!

Going through my journey with this truck and wanting it to stand out and be a fun daily driver I have noticed that it may be to my detriment to do bolt on things to the engine. I have a few things in mind that I want to do asap but I'm pretty concerned about voiding the GM warranty. After some digging around I found that GM will void if the aftermarket part is detrimental to the engine, which has a ton of interpretation, but I don't see the mods I want to do as being that. What do you guys think?

Mods:
PPE Resonator delete -PPE Delete
S&B CAI - LZO CAI

Pretty basic stuff I feel. It just increases airflow and makes some cool sounds - which is what I am trying to do. I am not really interested in performance upgrades, the MPG upgrade might be cool, but its more sounds and fun of the truck.

As long as it doesn't say "Banks", you'll maintain your self respect and that of your peers. Always remember, if you want Pedal Sphincter results, just press down on the pedal quicker and farther...No installation required, no engine codes set.

Care to elaborate? I don't know a ton on the LZO engine so anything that folks can provide would be awesome!

Alright you win. Haven’t heard that one yet. There’s gotta be a bumper sticker or something saying “paint loading” or something.

It used to be that drivetrains were pretty basic and straightforward, that is no longer the case, if you don't have any issues you likely won't have any issues, but if there is a problem they will definitely point to any modification from stock for warranty purposes, none of us could afford to sue under moss magnuson warranty act, even if we would likely win, they have a lot more money to fight with.

I happen to like some of Banks stuff, they have fallen behind on some development since they got in bed with GM/Defense, but overall most of their products are pretty good.

IMHO/YMMV

Ok, here's the skinny...for real...The DEALER makes the decision on warranty issues. Yes, they have guidelines, and yes, they get audited by GM from time to time. If you bought it there and get it serviced there and have a good working relationship with them, they will take care of you...Unless it's something crazy like a supercharger or something stupid like you took it apart yourself and can't get it back together.

I am employed in this industry in a capacity I won't disclose. Here's two ACTUAL scenarios, similar but with different outcomes:

1) Customer comes in with a check engine light. Diag discovers the addition of XX-brand pedal modifier. Remove modifier, clear codes, all is well. Customer stops by, they inform customer of the problem, customer states maker of such device said it would not cause a problem. Tech educates customer on how that is NOT always true, customer asks tech to tear it out and toss it. Customer tips tech $20 for information, tech leaves off ticket the part about it being there, customer isn't charged anything. A warranty claim is made for diagnosis with the repair being, "Loose connector".

2) Customer comes in with a check engine light. Diag discovers the addition of XX-brand pedal modifier. Remove modifier, clear codes, all is well. Customer stops by, they inform customer of the problem, customer states makes of such device said it would not cause a problem. Customer then proceeds to tell anyone that will listen how he knows everything, the interwebs forums know this device is perfect, the tech is an idiot, he want's it fixed. The tech unplugs the device, clears the codes, sends the customer on their way. Service Director inputs into vehicle records what they found, part voids warranty for unauthorized modifications. Customer has another issue, takes vehicle to a different GM store and they refuse to warranty any work on it because of the previous service notes. Customer calls GM and GM backs the dealer...Customer goes out onto interwebs and tells everyone how rotten GM is because they won't fix a problem caused some shitty aftermarket part.

See the difference?

I’ve been buying my Chevys from my neighbors for 8 years. He treats me well, I buy from him - repeat. I know the owner of the dealership. I wonder if I should just chat with them and ask about harmless bolt-ons. Im not looking to add tune or a SC, just want a little more fun out of the thing.

Thank you for the scenarios and your opinion!
