   Depends on the ECU algorithm.... But if the MAF is being used short term   
   while the O2 sensor is averaged over a longer term, that is what will   
   happen.   
      
   Deliberately forcing your engine to run rich might get you more power but   
   it's not going to make your catalytic converter very happy.  And in many   
   situations will not get you any more pwoer at all.
