I just tuned my 2002 mustang gt with the SuperChips Max Micro Tuner 1725 for the "Performance" tune. After the tune the car is idling differently. After you give it gas, the car will fall to an idle of a slight hair above 1k rpm and just hold it there for about 15 seconds then it will fall down to the normal idle of about 800 -1k rpm. This happens when you are driving also if you are rolling to a stop with the car in neutral idle will stay at 1k rpm or slightly above, then once the car comes to a complete stop the idle drops to normal 800-1k rpm. Is this normal ??? If not.. what could be wrong?
