thx mrs.

 

Im guess if you get these tunes they void your warrenty? I really want to get a tune but i dont want to lose it. this place is about 30 minutes from my house and there are TONS of cars and trucks around that have been done. http://www.madtunesracing.com/index.php

 

Not an automatic void. If you take it in for warranty work and the dealer finds it,then they could void it. Depends on your dealer and maybe your relationship with them. If you decide to get an aftermarket tune, then it's a gamble while your under the manufacturers warranty.
