You could try disconnecting the battery and follow the procedure in your owners manual for resetting the computer.

On my 05 you disconnect it for a few minutes when the car is cold.
Start the car and let it idle for 20 minutes, then turn the AC on and let it idle for at least a couple of minutes.
Then you drive it for 10 or more miles.

Let's back up a second. You have an aftermarket xpipe and the car has the stock tune?

Nope, re-read the post. He saying the the wires were crossed, front to back and back to front.

I would try what was already stated, disconnect the battery to reset the CPU as per the manual.
