I just installed a new procharger d1sc and new 255lph inline pump. My problem is that when im at idle I have about 60psi of pressure but when I get on the throttle the pressure drops back to about 40 (stock, i think) until the fmu kicks in. I tried unpluging the pump and the pressure goes back down to 40psi at idle. Has this happened to anybody else? Did i plug it in right? also I have a stock fuel pressure regulator.
fuel pressure too high with inline pump?

You better get an adjustable regulator. The stock one is pretty lean 36-38lbs. It shouldn't do what its doing- not working properly.
i dont know snot about the Blowers, FMU, timing retard units, etc. but i agree that an adj FPR would be a good idea.
i must be missing something - you could have a 1000LPH pump, and if the reg works, it will stay at whatever pressure you set it at. weird. good luck.
