You are launchin at 7000 rpm? What are you dropping your tire pressure to? I run 15.08 @ 93mph. I launched at 5000 rpm and got major wheel hop. My 60' is 2.5. I did burnout before, that might be part of the problem. where are you guys shifting at? I think I should be in the mid 14's with a header cat and CAI with stock exhaust.
