Fuel Pressure drop, takes a while to prime 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.

are you 100% sure its not leaking in the tank from the pumps rubber tubing?
under pressure the gas will squeeze between the rubber hose clamps if they arent tight enough
