It may have a fuel program of it own, but the fuel pump relay is controlled by the PCM anyway. Your programmer may want control of the pump but I doubt it's going to run all new wiring to the pump when it's already in place. What your saying is just not making sense. Regardless of what kind of injection management system you use, it needs a fuel pump and even if it wants different pressures, that's done at the engine. Unless your installing another whole fuel pump, you will need that one and it's wiring to control it.
