I would try to find a tune from someone else that is running the same MAP you are, and copy the MAP values to your tune. Are you changing the values under engine diagnostics, airflow, map sensor, map sensor linear & offset, etc? I know you changed them in the scanner, but how bout the tune? Maybe double check it, you could have changed it and it didnt get saved or something wierd happened, always good to double check. And there are plenty of 3 bar tunes to sneak a peak at to see if you missed something. G/L
