[QUOTE="Black02GT, post: 15636037, member: 23818"] Don't have all your answers but... FPDM has one output that runs both pumps. The positive lead is constant, the FPDM pulses the ground to vary duty cycle. The voltage question is tricky, the voltages are more or less what you set them to in the voltage table in the tune. I believe it's based on load. Is your tuner comfortable with this EEC? You have to scale a bunch of stuff from stock when you change injectors, or more importantly the MAF. [/QUOTE]
