Throttle Actuator Control triggering Failsafe mode

Hey folks. Ever since my ProCharger install on my 05 GT, I've had trouble with my car going into failsafe mode anytime I accelerate from a 60mph roll on the highway. Finally, last night on my way to my parents' house, I threw a code. It's P2106, meaning the Throttle Actuator Control (TAC) System is stuck open, so as a preventative measure, the car forces you to drive slower, thinking you're going to accelerate uncontrolably.
Does anyone know a remedy for this? Might something be unpluged or not hooked up right? Are there any TSB's about it (I think I remember someone mentioning one) and is there anything I can do myself to eliminate this very annoying problem.
Thanks,
Kris Horton

I had the same problem and the dealer replaced the throttle position sensor. I was getting these codes
P1000 - OBD systems readiness test not complete
P2106 - Throttle actuator control system - forced limited power
P2135 - Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation
No problems ever since. Read about it here:

So if you were to get a tune for a CAI, and later down the road you decide to change gears, from say 3.55's to 4.10's, you would need to retune? I thought that the Xcal 2 and the Predators would let you do this from the handheld.

Hey Kris,
Different issue, but, does your fuel computer still work correctly with the blower and SCT tune?
Also, when you get on it and let off, does it feel like the car wants to keep going a bit?
Thanks,
Brad

I got the same 2106 code and a 2111 code when I installed my new throttle body. Come to find out, I didn't tighten the throttle spring tight enough so it didn't spring back into the idle position. Once I tighten it up, away went the codes...
Now I just need to get a better tune, because she's not running the best because of the wider openning.
