PCM Tuning- negates Factory Warranty?

[Brianb231]

Hey Guys,

I just bought a 2006 H2 and put 37" tires on it. I was wanting to have my PCM tuned via laptop locally in Seattle. I am concerned that it may become an issue if extended Warranty work is required??? Does anyone have the real answer to this.

I apologize if there is a post already on this. I searched but did not find any.

Thanks,

Brian

DUDE, just get a handheld programmer like hypertech or the like and be done with it, set it back to stock if u have to get service

I have heard that those handheld plug and play tuners are not as good as having someone plug in with a laptop and road tune it? Is that true?
