what engine is there?
what EFI is there if not EFI its a carb, what fuel system is this?
sound like TBI injection,
the regulator is tested, for presssure, fuel line presssure,
using presssure guage, and is based of altitude, not throttle angles
did you check the ECU for DTC error codes yes, flash codes (blink)? that is first.
if he ECU is in limphome mode it will run rich as pig even with 3 new FPR regultors replaced.
