To tune or not to tune - worth voiding the warranty?


Recommended Posts

Seriously on the fence here. Currently have 24,000 miles in 8 months on my Sierra and getting the itch to tune. Custom tune is going to run me $450 Dino tuned, really want to get it done but not sure if it's worth voiding the warranty. Would you or not? Thoughts?

That's the main reason the only thing with the engine I've done to mine is exhaust. If you do the tune and something goes wrong with the engine (especially internals) you know they wouldn't cover it. My opinion is to wait until the warranty ends then go crazy. I remember when I wanted to do the exhaust (still all legal) I even called the dealer I got the truck from and they basically said not to do anything to it. I know that's just to cover their own ass. From what I hear they would have to prove that your mod is what caused the problem. But, I think it's easier to void a warranty, especially on a truck or sporty car like a Camaro or Mustang. Being that this is my 1st anything with a warranty I guess I'm the same as you and worry a little about warranty.

 

I now after being on here a little I want to change out my gears to 3.73 which I doubt will void anything. My luck though an axle shaft goes out, but I'd risk it lol.

I wouldn't say they are dogs without a tune, but I did a can tune, glad I did. GM has to prove the mod caused the failure. Go with a name brand for backing if needed. Ive been on different forums for years with different cars and trucks never read a warranty problem with a can tune yet on a gas tune.

Well next question is I've always had Black Bear Tunes and loved them, problem is they can't tune my truck until November.

 

So I found this guy in Houston, anyone ever heard of him?

How does his tune differ from what Blackbear offers?

I think it all boils down to money: are you willing to pay for vehicle repairs if the warranty gets voided? With as many problems as these trucks have had so far, personally, I wouldn't touch a thing until it's out of warranty. But that's because I'm not willing to pay for powertrain repairs that occur within the warranty period regardless of whether the tune caused them or not (I know it won't). I just don't believe a truck in this price range should have major engine or transmission repairs before 100k miles minimum and GM hasn't proven that won't happen. I had a 2007 that was plagued with issues and 2007 turned out to be a bad year for GM. With the way these 2014's are shaping up so far, I'm not sold that this vehicle won't have major problems before 100k miles.

Id been driving mostly GMs for 40 years, never blew an engine, lost one transmission on a trailblazer ss with a tune. They fix it under warranty, they knew I had a tune just reminded me to remove it. Im a hard driver, some of them I raced. Im not going to live in fear. The salvage yards are full of engines. Id been tuning since tuning been around.

Mine is tuned. Even had to take it in for misfires last week (had a bad spark plug). I returned the truck to stock tune settings and brought it to the dealer.

 

They did all sorts of data logging and code pulling and had laptops hooked up to it for 3-4 days. Never once did they say anything about the truck being tuned.

 

Just do it.

Cool, what tune did you go with?

I used a diablo tune from monte ss, that being said. I'm pleased with it,especially the torque management aspect and drive-ability, but I'm looking for more... :freak:

 

And yes I said a non tuned truck exactly like mine, is a dog comparatively, no other way to describe it.
