WOT fuel issue? 355 with Ford 30 lbhr injectors, custom cam, ported heads, etc.
In the driveway everything still looks great
Idle 40 psi
Idle with pressure regulator vacuum removed and plugged 46psi
Driving around steady speeds IE in town or 80-85mph on the highway 36-38 psi
Punch it during steady speed the pressure jumps up above 40 psi but it drops quickly
Underload at WOT it jumps up to around 42-44psi but it quickly drops below 40 psi to maybe 36 psi but it could be a little higher or lower it's hard to watch gauge and road at same time.
Is it time for an aftermarket pump, is the fpr tired? Looking for suggestions.

time for a racetronix kit. found out my pump was bad on the dyno. it would only start to fail at WOT. don't go WOT until you get a new pump u may get a little too lean and cause some serious damage.
