i put the diablo sport and jlt on today and i have to tell you i am not impressed. i think it must be the wrong tune. the car falls on its face after shifts then finaly wakes up and pulls up top. it does not feel any faster than stock, in fact i think its slower. i installed the 91 performance tune.

did you just install the diablo tune? or did you take it to a dyno? what year is your car? i picked up 16rwhp with my jtl,diablo, and throttle body.
