2 weeks ago at the same track I ran a 13.3 stock as a baseline. At just under 1000 miles on the odometer I installed the stage 2 parts and tuning from Cobb. I went back to the track to see the difference and made the following passes. These were the 3 best slips of the day out of 7 passes. The slowest pass of the day being a 12.7 due to a bad launch. The best pass being a 12.42 @ 109.44mph with a 1.686 60'

I am extremely impressed how fast this car has gone with little mods and OTS tuning. In the spring I plan to get the car pro tuned and possibly put in a clutch more suited for drag racing. I am 100% sure low 12's are possible with some more passes and a pro tune

DCCD was in auto
T/C was off
Shift points were 6100rpm
Launches were around 5800 rpms
Did not shift out of 4th gear, probably could have yielded higher trap speeds if I did but was shooting for lower E.T's. I was around 6500rpm through the lights.

Video of the 12.44 run will be posted soon!
