On higher boost with the transbrake it will bite REAL hard then unloads. Definitely wheelhop, though that might have been in part attributed to running first thing when they starting line was prepped really well but 20 feet out was very cold. I run 17-18 in the tires. I could get away with low-rpm launches when I had the whipple but if I don't have the turbo spooling right away then the 330 SUCKS.
ill pm you.
