One of my buddies has a 98 5.7 vortec that is running on 7psi through a powerdyne S/C. It is untuned but he want's me to tune it. He said he mainly wants the speed limiter removed and rear o2's turned off (easy enough) but with him paying for it, I want to help him out a little more than that. What tables should I be changing for him to get the most out of that 7 psi???

Thanks.
