would a moderate performance increase in engine rebuild call for upgraded injectors?

 

Well, you have to consider the entire system. If u have a high flow pump, fuel pressure regulator, and a tuned ecu, then you would want the injectors to be as good or better than the potential output of the pump/ regulator. Simple bolt ons, however will likely have no effect on your power of your ecu isn't tuned to compensate.

 

Man this is super vague and posted in the wrong section lol.
