OP was asking if the default could be changed to the TC off. If a tuner could do this it would cost you a lot of money for such a simple little change(not having to reach and push the button). Frankly, I believe the TC has saved my a$$ twice when I was over driving on the street, since I've owned the car. I only turn it off when I'm at the track, visiting the twisties, or showing off haha.
