I just added a kenne Bell BAP and larger lower pulley 9.55" up from 9.1" and I am noticing my O2 voltage bouncing around. The scan file I have attached has several 1st, 2nd, 3rd bursts. I am running two cans of Torco in this tank of 92 octane and I'm not sure if this is causing the car to behave so differently. I also changed my PE settings to model another tune that had a BAP installed since I have yet to sort that setting out. I was hoping to get another set of eyes on this. I don't do this enough and this is making me want to start over. Any help is appreciated. Thanks.
