...no PCM tune as of yet. Maybe in the future.

 

I'm assuming these mods have no affect on the factory warranty? Just got my H3 yesterday and would like to do some mild performance mods..

 

Same question, got my hummer 2 days ago. What does this do with any warranty? Also, what is a "PCM Tune"

Thanks

 

Somebody just shoot me...


Okay, The mods. such as Cold Air Intake systems, Cat-back exhaust and PCM tunes will not affect your warranty in anyway...A little thing working in your favor to ensure the dealers honor warranty claims unrealated to your mod is call the "Magnuson Moss Act"...If you ever have a little lip service from your dealer, just drop that tid-bit of knowledge on them..do a google search on it and learn more.

The PCM as GM calls it, is the computer of your car...It is easily removed and reprogrammed for optimum performance..Read the the section called PCM....
