i have the same problem with the Walbro HP 255, so i bought a FPR. I havent istalled it
yet but i am thinking that the Walbro has raised the fuel pressure too high.

Even with the bigger injectors it would still run the same, i replaced just the pump on
my car first then the injectors (WRX 440's) but just with the pump and stock injectors
it ran the same (bad).
you are doing something wrong then...if you have the car tuned wrong (or not tuned for that matter) that is the problem, not the pump. the pump only ups the capability of the pressure - so in otherwords your pressure shouldnt really increase with just the pump. like when i installed my pump, until i adjusted the pressure of the FMU, it was still at the same pressure.
