TUNING AND WARRANTY

[jzaldivar]

Im sure this has been asked before but I have a new 2015 that I put bigger tires on and am wondering if I get it tuned will it void my warranty. There is a local guy that tunes trucks but I am afraid of warranty voiding. Please help

This has been talked about extensively in a bunch of other threads..

It could ... Depends

 

If your transmission it engine goes and they find that the pcm has been flashed ... You will probably not be warrentied

 

You can fight them and prove all you did not was alter the speedo calibration ... But that might not work out either

IT really depends on the dealership. I've taken my car to some that didnt care and some that wouldn't touch it. Modified and tuned.
