So I picked my car up from the shop and my guy mentioned that when he took the car for a quick test run it wasn't responding properly in high RPM's. I took it for a spin and put the pedal down in 4 gear and at about 4K RPM's the car sounded like it was blowing through the exhaust and the ASC turned off along with the service engine soon light came on. My guy believes that it is probably the Throttle Position Sensor because the voltage from my AP shows the numbers being only 87% max. Any Idea's? I do have a couple mod's with an off the shelf map from cobb. Everything seems great but as soon as I hit that high RPM point everything goes wrong.
