For those of us that want to stay in SCCA Street Prepared class instead of going to Street Modified right away, it would be interesting to see what gains can be had without touching the turbo, boost, and BOV/wastegate. Just intake, exhaust, and non-boost ECU changes / S-AFC II type stuff. While having an SBC-ID and setting it to factory settings would probably work in my region, I'm sure having one anywhere near the car would get you protested at nationals.
