Cool thanks... It is really 10 psi of fuel per 1 psi of boost by any chance? Woohoo, metaljim comes through in a clutch. Points for you.

Actually, its should be about 5psi of fuel per pound of boost. You should have the static pressure somewhere around 45. So at max boost if your fp is 80psi, then its 5:1. 80-45=35. 5:1 gives a 35psi rise at 7psi. 7*5=35.

BTW - thanks emoji
