Default GWPstg2fuel pres ????

Have GWP stage 2 kit installed. Car ran great. 2 Hobbs fuel pressure switches malfunctioned. Bypassed Hobbs switch. Car ran great. Now my fuel pressure drops even with no fuel pressure switch from 72 to 50 pounds
in boost. When ignition switch is in run position, stock pump only, pumps to 60, and settles at 48. When ignition switch is in run position, both pumps, pump to 72, and settle at 0. Originally fuel pressure stayed between 65 and 72 pounds under boost with both pumps. All wiring, relays and fuses are ok. Can also hear both pumps running. Does anyone know fuel pressure needed, and best method of maintaining the fuel pressure needed?
Thanks

Mine stays between 55 and 58 PSI. That's where it is at crusing. Brief dip when I WOT it, but it immediately hops back up to nearly 60 PSI.
