I'm new to the forum, and modular mustangs. I just bought a 2002 gt with a 04 cobra motor with a 2.3 whipple. I'm losing fuel presure when it starts to make good power. It has 60lbs injectors with twin gt supercar pumps. It was making 572 hp, now its probalbly less than 400 hp. I pulled the tank and I noticed it still has the pprv in the tank so I ordered fuel line to eliminate that as a potiential problem, but I was told it could be the fpdm not uping the voltage to the pumps. So if anyone has one I could barrow just to see if thats the problem that would be a great help. Or if you know of a way to test them.
