I already have a tune, that tune is to rich up top for the exhaust setup. With the new y pipe design I'm allowing for more backpressure thus running rich. I don't think the sensor is faulty though if you run rich over time you'll burn them out, a fact I learned the hard way. Is it possible that the ecu corrected itself, leaning out the afr causing the light to go off? I guess there is no way to confirm the code is gone until I drive the neccessary 200 miles to see if the CEL comes on and scan it again with the OBII.
