The car should have a way to turn it off... I know that with a tune you can disable it for good... Whenever someone turns of trac control and they turn the car off then back on it will be back on... A tune can make it stay off.

There should be a button next to the power plug that says TCS
I have an 05 V6 premium with this & on the top of the center stact there's a button marked TCS & this turns the system off & on. When this is turned off a light shows up on the dash to show it's turned off (just like if you turn off the overdrive). If you do not have the TCS button your car doesn't have this option.
