On? Off? Is it like switching off the posi? Should I have it on or off when I get next to a tuner at the stoplight? Thanks.

By the way, I'm only a newbie to this forum. My first mustang was a 67' Fastback GT with a 390, toploader, factory front disk brakes and 32k miles. I paid $800 and yes I cry when I think what it would be worth now. (bought it in 75' before most of you guys were born)

2004 GT, auto, bone stock for the time being.

TCS off when racing...unless you want it to bog and prevent the win not that it is impossible to race with it on but JMO.

Strange, I have tried it TCS both ways and don't notice a difference.
