I currently have an off-road h-pipe and I was wondering if I use my hand held tuner to turn off the o2 sensors would this affect the tune that is on the kb chip that was supplied with the supercharger? The other question I have is I've read that the optimal a/f ration should be somewhere around 11.2-11.7. What is the norm while at idle, because mines is jumping all over the place in between 14-17. Even when driving(taking it easy not shifting above 2k before I get a dynotune) it was still acting crazy. Would the placement of the a/f ratio sensor or off road h pipe have an affect on this?
