    Fuel pump would I max injectors?

    I have a walbro 255lph pump I was wondering if it'd max out the stock injectors on my 02 wrx. I've gathered parts for a turbo swap but I need a emergency tune cuz my car is running to rich and is bogging down and stuttering and jerking due to the tune I have on it if even threw a code due to this problem.

    The fuel pump has absolutely nothing to do with IDC's.

    +1. You should do some reading on fuel systems.

    The injectors don't care how much flow is going past them. As long as there is fuel there, and it's the right pressure, they'll inject the fuel as expected, for the most part.

    ... If anything, you'd overload your fuel pressure regulator... Which you won't.

    Is there any reason why you are swapping the fuel pump right now? It most likely won't make a difference in your tune, especially with stock injectors.
