My 2007 harley was fitted with 'race tuner' fuel management system. I started experiencing stalling and general rough riding conditions which required several expensive visits to the dealer for a variety of misdiagnosis. To make a long story short, the race tuner was faulty and once removed my problems disappeared. You may want to swap out your power commander, just to rule it out as the source of your problem. I wish I had done that $ooner.
