I made 298whp/250wtq with the supercharger/110mm pulley on the initial remote tune from StageFP. It's a little lower than I was hoping for, but that just means I have a little more work to do. AFR trails off near the top of the RPM range and power/torque gets a little choppy above 6k.
Not to mention the belt slips from time to time on cold starts. Anybody else ever experience that?
