I have the Walbro pump, and since I finally replaced the old old old dirty tank sock, my pressure jumped up so it averages between 39 and 43 psi off boost, and on boost at 50 psi ( I have a 1-1 rrfpr).
Runs great finally though.
Is my fuel pressure above normal?

You don't have an RRFPR. You have an aftermarket manifold-referenced FPR.
What pressure do you have your FPR set to?
Standard fuel pressure on our cars is about 26 psig at idle, about 36 psig at WOT on non-turbo cars, and about 45 psig at full boost on turbo cars. More precisely, it's 36.3 psi above manifold pressure.

The FPR doesnt have any settings.

MSD Boost/Fuel Pressure Regulator
PN 2222
It doesnt have a setting unless the bottom set screw makes it adjustable. Maybe I can check.

Heh, yeah I looked into that fpr. If you leave it connected as it is, the screw will adjust the fuel pressure to a fixed pressure. If you install the nipple like dealie it will use mainfold pressure to adjust fuel pressure higher or lower than what it is set at.
