Re: O2 READINGS!!!!!!!!!!!!!!!!!!!!! O2 sensors at 14.7:1 Air Fuel Ratio should be fairly accurate but the farther you stray from that number the less accurate they are. To be in good shape I would recommend trying to dyno the car and use a wideband O2 setup to see what your true air fuel ratio is. Then you can go back and base the information off of this. Maybe someone else can give you some more help. I'm very new to tuning and don't know a lot about it but this is what I have been told.
