question about fuel pressure on my DD
 

I have a '93 Ford Probe GT :barf: for my DD and it feels sick above say 4500 rpms. I used to have the same car back in college and it pulled up to redline (7K). Anyways, I put a mechanical fuel pressure gauge in 2 spots: one after the filter before it reaches the fuel rails and then I moved it to the crossover line going from the rear fuel rail to the front rail. Anyways, I read about 30-32 psi at idle which stays there up to around 4000 rpms and when at WOT above that it steadily drops to about 22 psi. There is a fuel pressure regulator on the rail right before the fuel returns to the tank. I tried the Ford Probe message boards but the level of knowledge there is lacking :eyes: I'm trying to determine if the power drop is fuel related. The pump has 140K miles on it if it's the stock one and the filter is brand new. I can try an AFPR and dial it up to see if that helps otherwise I'm thinking new pump. Can you guys help me out?
TIA

you could put a wideband on it and see if your AFR is dropping up top.

That would require too much work for this pos :)
