Gentle creatures of the 2 doors,
Current setup. Return fuel system. Stock 2.5L Rail. Stock Regulator. 42lb injectors. Walbro 255lph GSS342 (Fuel pump has been insane loud since day one very whiny outside of the car. )
My fuel pressure is dropping at WOT at roughly 5.5k~ RPM or greater. From 60~ PSI down to about 40 (Maybe less) Causing the car to lean out, basically have no choice but to let off....
- Regulator and rail have maybe 2k miles on them, fuel pump has maybe a few hundred miles on it. Running a stock style sock. New fuel filter. Gas tank is full.
- I have a fuel pump jumper relay to run fatter 12ga power direct from the battery.
- voltage is good all the way through the rpm.
I don't know what the hell is going on.
