This is simple, ProM or not that is....
ProM LIES to the EEC, that's their method of "tuning". The MAF tells the EEC the airflow is "x" to get the AFR "correct", even though the airflow is REALLY NOT "x", but "z". That causes the EEC to INCORRECTLY calculate LOAD, therefore it will use the WRONG look-up tables (for "z", the REAL load).
End of story.
