i'm interested in buying a tuner but i cant decide what i want. mainly i want to get a little more power but i dont like the torque request system and like to down tune it to get more of snappy shift also a little more throttle response out of it. my plans are cold air and probably a cat back dual. and eventaully a leveling kit to run a slightly larger tire. so what is everybodys opion on the superchip and the diablo.
