I just bought a 1993 5.0 Gt with a paxton Sn 92 blower installed. The car runs great for the most part there is just one problem. It has a fuel pressure gauge installed and at random times the pressure jumps between 40 and 60 psi. i can tell that it is not just a gauge issue because you can feel the change while driving. there is a paxton FMU and a BBk regulator installed. one person i talked to said to remove the FMU and run it without. I am not sure if that is the best thing to do. Any help would be appreciated.
