Fuel Pressure HELP!!
 

Vortech S-Trim 10 to 12lbs of boost mostly stock motor low mileage. Wideband, Fuel and Boost guage.

• 75mm Mass air conversion
• GT 40 intake,
• 36 lbs. injectors,MSD coil, 190 pump and Trex pump
• Stock cam with 1.7 roller rockers,
• Ported and polished E7TE heads

Its been dynoed at 316HP at 3900RPM then DYNO machine cut out. But I had a serious fuel problem, anyways fuel pump is ok, maf is ok but guy said might be your fuel pressure. Ive been playing around with it and seeying results but as you all know WOT on regular streets with 400HP is asking for it.

What are you guys running for fuel pressure at the rail no vaccum?
