Soo i bought the stage 2 alternator voltage booster from zzp, and i installed it, and it gave my car 15.60 volts, but then my dic light kept blinking and flipping out soo i took it out before something would happen to it. Well i should of just bought the stage 1 and called it good. The stage 2 kit is for race applications only it said, idiot me. So that was a waste of money since i cant take it back.
