    Upping the fuel pressure will cause you issues. Lambda is gonna see too much fuel for a given injector pulse, tell the ECU which will then try to pull the fuel trim back. But prob won't be able to pull it back far enough.
    You'll run too rich, lose power and prob throw some error codes.

    Usually the only reason for swapping the FPR is if you've had a remap on standard injectors and they cannot supply enough fuel as required.
