I'm running a 2005 5.3 with 706 heads, head studs and an 02ls6 cam. I just got the car running and i'm on 6psi with a 76mm turbo. I have 91 octane and I'm running 16* timing in boost. Can I get away with more do you think? And do I just add a degree at a time until it knocks and then back off? Whats the best/safest way to add more timing in the car
