With the TCS off if I am taking a corner and give it gas, it's like the engine pauses then it decides to downshift....

UPDATE: Earlier today I gunned it going straight and it did the same thing...

Should I get the car checked out for codes??

 

Just reset the ecu. It is in it's "I've learned not to drive fast" mode. You need to clear the learned ecu values. After you do, get out and do a few WOT runs (pref on the interstate), so that it will learn to downshift faster.

 

Or just pop it in tip and choose the gear you want.

I know around here being stuck in traffic 95% of the time the computer forgets how to get up and go at times. Just slide it over to manual mode and enjoy!
