"I purchased a mass air flow with cooling and a air induction kit. I started receiving engine light errors. My dealer would reset the codes and I would go on. Now, I can find the reasons. I also used the customer service for help. I was told how to stop the codes from continuting. The dealer replaced something on my car and that is stoping me from performing my performance tune. I have an appointment to get this concern fixed with the dealer. Then I will do the performance tune. They were so suprised that I knew what the codes stood for." —Donald S from Indianapolis, IN bought a Jet Performance Programmer for a 2004 Pontiac GTO.
