Just keep turning the RPM up until - it slows down, it won't hook, or it goes too high. Of course, getting after it, it may want to have some suspension/shock adjustments to take full advantage of it.

Our pro tree car had no chip in the low side, went 5800 on the mat and liked it.

Super Stock car I help with we tried some stuff in the past. Went higher and faster every time we turned it up. I think he has it at 3600 now. We did some up grades and I think it could stand some more. But it's consistent, hooks, has a good 60' and not violent, so he hasn't fooled with it.
