    I just had my tranny swapped from a auto to a manual and my ecu was reflashed. I now noticed that my car is driving like it has only 2 cylinders and it is very very slow like it has no power at all. I have and 07 with about 500 rwhp (procharger).

    When the car is off, the throttle body works fine, but when you turn the car on, the throttle body only opens a quarter of the way. Can anyone help me with this.

    You need a new ECU.
