As I said in my last post, the PCM can get an idea of when the MAF is reporting values that aren't reliable. The MAF isn't the only sensor that measures incoming airflow. Did you get the fuel trim rich code with the Stage 2 tune?
Its worth a shot, cleaning the MAF, I just wouldn't expect much. Most MAF sensors have the ability to superheat themselves to burn off anything that may contaminate the sensor.
