    GM had us Post in our shop office that signs of any aftermarket programming will void the warranty sorry. You up the power like that and the warranty is void.

    Ashley this poster john boy is talking trash.My husband has a power programmer on our 2007 silverado and was told by the dealer it could void the engine warranty only period.This clown john boy wants you to believe it could void all the warranty on your truck.After having the programmer installed the dealer told us lots of people have the programmers and they have NEVER had a engine failure due to a power programmer.I will post the website were he bought his programmer. http://www.autopartswarehouse.com/search/?N=0&Nr=AND(wpn_tl_name:Engine+%26+Drivetrain,wpn_cat_name:Power+Programmers,wpn_scat_name:Power+Programmer,part:Power+Programmer)
