Ford PCM's use PWM to fire injectors. The impedance of the coil inside the injector itself has a specific rating to flow the flow charts in the PCM. If the impedance rating doesnt match you can severely overfuel or under fuel a cylinder with the wrong injector.
BTW, FMS makes the injectors I would need @ $600 set.. Ouch.. Maybe time to setup for pump fuel..
