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.
