Around 370ish WHP if you were going to just run 18-19psi. For the 387whp run, all we did was turn up the boost and added 100 octane to prevent any possible detonation. It spiked around 22-23psi briefly and held 21 psi to redline on that dyno run.

Frankly, this car is really quite fast for the street as it is. I'm running about 18-19psi when I drive it on 91 octane and I can break the 235 series tires loose on the highway at 55-60mph quite easily. The Apexi-AVCR boost controller is tapped into the ECU and can do boost-by-gear which definitely helps control wheelspin in 2nd and 3rd gear, but if you want to, you can certainly light up the tires by a simple button press on the EBC.
