FMU's are a band aid fix for poor fuel systems. Even the top notch FMU's are still crude in their operation. Best way is to size the injectors, pump, regulator and lines for your power level. 42# injectors will support 500 rwhp with a good pump and tune.

Fmu,s are to raise fuel pressure under boost.The lower the injector rating the higher the fuel pressure is needed for every pound of boost.If you replace your injectors you will need a mass air calibrated for the size of the injector you are using.The only way you can do this is if your pcm is calibrated to use bigger injectors then a fmu is not needed
