Nice setup...as for the tuning, just be carful running higher boost on pump gas, and esp without any timing control. Be VERY cautious when retarding timing with pump gas, because that will drive up your EGT's significantly. One or two degrees is fine, but no more than that IMO. If you have to pull more than that, you need more fuel octane, lower boost, or colder air charge. With my experience with a S16g, 93 octane, and 8.8:1 compression ratio pistons, 15 psi is just about the max on 93 octane and PROPER amount of timing(roughly around 15-17 degrees, NO retard). Its my opinion that running any timing under 15-17 degrees is not the best thing to do, for both power and and safety. EGT's get really hot under 15 degrees. Its ALWAYS best to run more octane than retarding timing. You make power that way..with more octane you can run more timing, more boost, and that makes power!
