I was running 8.3's that night, the "new" predator canned tunes seem to have lost me a crapload of HP........I typically run 8.0's getting a 7.9 once in a great while in the 1/8th......
Nice run. And speaking from experence if your running 12's an srt-10 will never come close. Could only get mine to best 13.6 @105. Don't know about the auto ones but my 6-speed is hard as hell to launch.
