not really, pump has nothing to do with injector size, the pump is there to meet the fuel consumption of the engine , the VCM controls injector duty cycle depending on fueling needs and of course fueling needs can surpass the safe operating limit for injector size

So there is no need to upgrade the pump then? Just injectors So when would you need a pump?

an upgraded pump is always a good idea, but you really wont need one till around 450 rwhp, the 01-02 injectors are good for about the same power range, the 98-00 cars will need to upgrade injectors around 400-420 rwhp
