Also, I've got the Performance model, which I believe also has that TCS thing, or whatever it is. The manual mentions being able to turn it off as well, but I can't find any button for it. I've found the VCS button, and there's a spot right next to it that looks like it could have been a button, but it's not.

 

The VCS button is also the TCS button, both functions are controlled by the same button.

 

So should you turn it off when drag racing?

 

thats up to you. depends if you like to go fast.

I forgot to turn it off on 2 runs. I got like 14.9 on one, and 15.1 on the other. with it off I stayed in the low 14s. it slows you down ALOT. I guess only if you spin the tires, but its obvious to me that spinning the tires a little loses less time than shutting off the power.
