Anything over 14.5 and you aren't driving it right. I ran a 14.2 at Gainesville bone stock everything in my 02. Rev up to about 4,500 rpms and let off the clutch a little but don't engage it yet. Let off the clutch totally on the 2nd yellow and floor it at the same time. Get a good second gear shift and the rest is easy. It just takes practice and patience.
