HELP! Which handheld tuner???
I currently have a jet chip and the thing is garbage. Ive had problems with it form the start and its about time i get rid of the thing. I know there is a diablo sport and the superchips tuner, any suggestions or comments on which one i should get. I heard that they can also change the shift point on the trans, is this true. I have a 2008 4.7 limited, please post what you guys think and help me choose the best bang for my buck. Thanks!
