why not? people tune there cars and trucks everyday or hook up a handheld tuner that changes the whole tune of the car, we swap parts that arent neccesarily meant to be on our trucks, do motor swaps, but plugging in a little device to make the motor more responsive bothers you?? hahaha hey atleast they give you a 30 day money back guarantee? but like i said it wont work on my truck so i cant tell how good it is but i have heard really good reviews about them i was just wondering if anybody tried one and what they thought?
