i also suggest the fuel pressure regulator, especially if you still have the original one on there. Now is a good time to get an adjustable one, no need in replacing that one with a stock one. }:~)

it sounds like fuel to me, but it is hard to diagnose over the internet. If you have a fuel pressure gauge, check the pressure at idle, and then at WOT, i bet it drops by about 19 lbs. this is what i would check first.

you should be able to hear the fuel pump running for a second or two when you first turn the switch on. If it isn't, then the pump itself could be bad, or the fuel pump relay, or even the EEC relay.

My fuel pump went bad and you could still hear it run. You need to check fuel pressure. When my pump went bad it was really noisy. Was more of a roar rather than whine.
