Ive been having a problem with my fuel pressure dropping when i get into boost. After I make a couple pounds, fp drops like a rock to around 30psi. At idle, its around 58psi. If the car has been sitting, the fp will be at zero and have to prime for about 45 seconds.
The car has twin walbros, 2nd pump is wired to come on when the keys on, -8 feed, aeromotive rails, earls filter, factory return setup & regulator.
Ive tried running without the gas cap per a friends suggestion and that didnt really help. Thanks for the help, i miss 6,000 rpm.
