it was a blast...just make sure your tires and everything is in proper order....i dont even want to think what could happen if a tire blew

I can burn you a chip with the limiter removed and some fine tuning for any mods you have.
My friends 91 Firebird TBI had a limiter of 115mph and when we swapped gears from 2.73 to 3.42 and the top speed went down to like 98mph. I fixed the prom and no more limiter (actually there still is a limiter, but it is set to 255mph.)
