4 factory injectors on secondary drivers?
Are the secondary injector drivers in the PFC capable of driving two factory injectors in parallel without cooking?
Trying to come up with a sloppy fuel supply increase using factory gear as machining stuff isn't an issue.

running 6 injectors is an old school mod, but it'll do it. i think you do need to keep the current around 1 Amp, so high impedance injectors are needed.
12v/15ohms = 0.8 Amps
12v/6 ohms = 2 Amps....

Was going to try more ghetto than that, mill/drill into the underside of the UIM and fit the spare primary fuel rail. If going to that effort I'll just buy ID1700 & 2600.
