i have a 12 second automatic convertable GT. 12.697@110mph is my best run so far. i was dealing with some transmission programming problems at the time, so i think it's a little faster now. there is still atleast another 20rwhp left for me to tweak out of the tune. i've also got 3.73's and control arms on the way. i'm hoping for low 12's on street radials.
