[QUOTE="Tom Schindler, post: 570335, member: 56140"] Your intake system flows as much as the most restrictive part will flow. The throttle body is the restriction in the system. Look at it. It is tiny even compared to the Mass Airflow Sensor (MAS). They claim the different calibration makes a difference. Honestly, I don't see how that is even possible. The MAS detects the ammount of air entering the engine and the temperature. If the numbers are accurate, how can a performance MAS improve performance if it gives the same readings a stock one does. Wayne knows more about the Ford system then I do. Maybe he can explain how and why a performance MAS works to improve performance. I am just using logic to understad how the system works. If there is a replacement throttle body available, I would say that would make an improvement. Unfortunatly the throttle body is much smaller then the stock MAS is. Where is the improvement? As I have said before, I have a performance MAS. I did not notice a difference between the stock and the performance one. Tom [/QUOTE]
