Fuel Pressure Decreases with Throttle...
So I finally got my fuel pressure gauge all hooked up. It's an Isspro Ev2, and I also have the Tork Tek OFV020 Adjustable Overflow Valve. At idle, the gauge reads 25 psi, which is what Tork Tek states it should be. But as I give the engine some fuel, the fuel pressure decreases, instead of increasing.. I have not brought it to WOT yet, but bringing it up to just over 2k rpm, with about 10 PSI boost, the fuel pressure is about 20 psi...
