2005 Mustang GT Erratic fuel pressure

I have a 2005 mustang gt 4.6L it has a turbonetics turbo kit on it. the fuel presure gage bounces around like crazy, it was ok and then one day it went nuts, I tried a mechanical fp gage and the fuel presure is really jumping around, i replace the fuel pump driver module and same thing? if i unplug the fuel rail presure sensor no change? the pump is stock and the fuel presure jumps around at idle and while driving?

your pump might be broken....
why are you using a stock fuel pump with F/I?
Replace it with an upgraded one, or a cheap stocker and patch it with a KB BAP
