Technically, a tuner does not void a warranty. The Magnuson Moss Warranty Act deals with this. Basically they would have to prove the tune caused the problem. if it went that far. I did put a hyper-tech tune on mine and makes the drive a lot better, less sluggish etc. And me personally would only get a hyper-tech. But then again I know the guys who makes most of the tunes including the one for my truck.
