2007 silverado classic 4.8 - throwing multiple codes.

[hookemhorns8504]

*My truck has the u7192. It is a 2007 silverado classic, 4.8. My tuner is v9r04.
I have had the tuner installed and running the 93 octane tune for almost 6 months now. Recently started recieving 3 engine codes, all relating to my t.a.c. module (throttle acutator control). I reinstalled my factory tune, cleared the codes and unplugged my battery for 3 hours. This got rid of the codes and it is running fine now. I drove it on a 100 mile road trip and it worked flawlessly.Tried to reinstall the 93 tune and it just brought the codes right back up. I do have a full 3" exhaust, underdrive pulleys, intake, 3" cutout, and 3.73. Not sure if any of this stuff will affect it. Any ideas?

It was also causing my truck to go into "reduced engine power mode" which makes my throttle completly useless...

I would start by installing the original tune and updating the predator. 9r04 is from 10-15-08. The latest is 9r13 from 8-11-10.
