Well, first i would like to say, Damn, my car sounds good. Also, my a/f gauge is a little funky. It's reading all the way lean. did i hook it to teh wrong wire on the O2 sensor? (none of them were labeled) There waere 2 white, one black, and one grey. I'm spliced into the grey. I seriosuly oubt that i am running that lean. Or could i really be running liek taht cuz teh ECU is freaking out due to the new pipes? And, BTW, i was on a pretty decent cruise tonight, and my check enging light hasn't come on once. Any input on the funky gauge?
