I just took mine in saturday and had the emission bs taken off and they put an H & S tuner in and I can't believe the difference. Mine is a stick shift and the guy told me he never did one with a stick. He said you best take it easy till you figure out what it will do. Supposedly went from 350hp to 600hp on wild setting according to the tuner book.
I have a h&s tuner. You probably have around 550-575 RWHP |
