tuning the safc with the stock o2 sensor is worthless and can be very dangerous to your engine, stock o2 sensors are not accurate at all. tune the safc with a wideband o2 ONLY, you can adjust a little but dont try to perfect the settings cause you wont be able too and you can run lean without even noticing it and do damage quickly.
