opps i meant to say if in partial it goes to - - - then your sensor is bad, and no matter if ur tuned or not its really hard to go - - - on 1-3psi with 550 cc injectors so u def need a new sensor not tune

If the sensor is sitting at 14.7 on the dot during cruise and not moving you have a shot sensor. Also to go from a typical 11.0-12.0 afr under boost to ultra lean (16.0+) thats more than likely over a 40% diff in fuel loading - thats pretty much impossible for a temp change or slight tuning change to cause. Youd have to have HUGE mistakes in the fuel mapping to cause this - In this case its more than likely a sensor issue.

Exactly, he would know in the case so otherwise the sensor is shot which is his problem but he knows that now.

No it doesn't. The only way to know for sure is to take a meter to the sensor pins to verify they are within spec. The sensor runs on voltage so it could be anything; short in the wiring, sensor not within spec, etc. Sometime even when the sensor reads within spec the issue could still be the sensor, the only way to cancel out the sensor is to meter it and try a new sensor to see if you are having the same results.
