Shawnp, his first couple of burnouts were pretty long, but even after making them VERY short, he was complaining about the shake. I think youre correct though. It's the tires biting coming off the throttle after the burnout. Hopefully padding the seat will help.
David, it 60's in the 1.15-1.16 range, 5.0's @ I think 138 at the 660 and 7.90's @ 169 at the 1320. Agreed, it's very slow delay. I run 1.117-1.126 in my Vette now that it's sorted out and figure this car should take that and more.....
