If you have no idea what pressure your spraying at that's probrably the problem. You pressure is probrably to low and your getting some surging. It wouldn't be a bad idea to put a remote gauge on your standalone fuel set up either. That would be a good place to start.

70-80psi when spraying? Where your jettings figured for that much fuel pressure? With a combination of that and a low bottle psi your probrably super rich making the car fall on it's face.
