this may not be the best advice but a new a kid that peaked out his dodge on a 60PSI gauge with no head studs and a hx35turbo the only problem was that he went through about 4 turbos so u can run higher but at ur own risk.

whats a safe boost pressure that shouldnt bother the hg? , since studs arent in the budget right now because I need a clutch soon.

35 to 38 max.
