40-50psi under WOT is fine.

cool . i was a bit worried as to how high i could go.im gonna take it to get a tune from alternative auto performance after i put the longtube headers so i think he's gonna play around with the pressure anyway?

40-50psi?? Should I be concerned if it hits 60 at WOT and full boost?
