All right heres the deal,I have an 88 LX hb stock from the intake down.I have a Trick Flow street heat intake,65mm TB,76mm C&L mass air meter,30# inj.,K&N conical filter, Vortech S-trim puttin' out 9lbs of boost,Vortech FMU,190lph intank pump,T-Rex inline pump,Holley adj. fuel press. reg. set at 38psi.My question is, how high should my fuel pressure be under full boost?It will hit almost 80psi.The fmu is calibrated for 12:1,Does this mean, for every pound of boost, my fuel pressure is raised 12 psi?
