    fuel pressure regulator

    Ok i have a 2008 challenger with 215 hp. I installed x charger and riva gen-3 intercooler. I also installed the 42# injectors and my mechanic is now installing the fuel pressure regulator. Now my mechanic is telling me we can put the stock injectors back on and he can
    adjust the fuel with the regulator is that ok or should i leave the 42# on with the regulator.
