I have one and it made a big diffrence. The tunes I have are stock, 80 hp daily driver, 65 hp tow, 100 hp, high idle, and smoke. If you have the stock hpop and injectors you might have a hard time running anything over a 80 hp setting and possibly even a smoke tune. I got mine from kenny at KT performance
. He was more than willing to answer all the questions I had before I orderd mine and if you dont like the tunes you pick he will reburn it.
