Default NA Fuel Pressure High after Pump Install

Installed a Walbro 255lph pump in a friends 2001 RS since his stock pump died. About a week later his fuel pressure is around 80-90psi @ idle. We've been trying to regulate pressure with a Paxton FMU and removing the stock FPR but that hasn't worked either.

Anyone got any ideas?

Thanks for any help.
