u could most likely run easy 7 lbs of boost...9 if u mod a few other parts...its more about how u prevent the detonation as well though, like u said...but when u put a certain amount of power through i think a good idea would be to upgrade the valvetrain...get some better rocker springs at the least...i would get roller rockers and the works though just so u have a clear consience that its not gonna fail cause of that.
