I have a 93' Mitsu Mirage, I wonder if I could swap that pressure regulator on it and have some improvements, where did you find that info ,.
Maybe my CAS timing is off causing the white plugs, I just put a new T-belt on so maybe I should give it a while, I just want bigger injectors, way to rich though you say.
I have messed with the plug in the MAF before and it runs better with it in alining the air.
I guess I should rewire the pump thanks guys.
