This past weekend I had the pleasure of installing Autometers' A/F Ratio Gauge. After the install when I first popped my car off my mixture was Stoich and then about 1 minute after the car was on it moved all the way to the last led light on rich. ??? I have heard that Subys' run really rich, but I didn't think it was going to give me a reading like that. My question is, is there any way to lean it out without getting a S-AFC or any other means of ECU tuning?? Any feedback is appriciated.
