I just installed a Ford GT (supercar) fuel pump into my 2002 Mutang GT in preparation for my ProCharger which goes on in a week or two.
With my stock fuel pump, I saw the typical 39-43 PSI of fuel pressure, which would drop sharply to around 25 PSI when I left off and then punched the gas when shifting.
The Ford GT fuel pump is making the pressure go all over the place. While accelerating in gear or cruising, the pressure is more or less normal, but when shifting it drops dramatically (often to 0 PSI) and then spikes to over 50 PSI. The drop in pressure usually occurrs right when I'm stomping the gas again in the next gear, but since there's no pressure, the car falls on its face for half a second until the pressure comes back.
Is this normal, and should it be fixed when I get my new tune?
