Actually on a race gas tune, you would first lean out the AFR's. I'd then add boost, then tweak timing. Then maybe a little more boost. Hey, what can I say... I live up to my screen name! Just tuned an Evo 8 on 91 octane pump gas. Made 414whp, running 26 psi, without a hint of knock. I really prefer to make power with boost (rather than timing or lean AFR's) as long as the car has a turbo capable of running the PR's needed efficiently.
