So I was at the track last night for the first time since I installed the Paxton prior to that I hit a 12.7 with full exhaust and tune last night I hit a 12.1 at 119 mph only did 2 runs first run was a 12.2 at 115 mph these 3:73 are killing me with shifting into 5th to cross the line not to mention my stock clutch!! Guess I know what my next upgrades will be!!
