You are confusing TRC with the rev limiter which is there to stop you melting the bearings and generally wrecking the engine if you plant your foot when there is little or no load. TRC in snow mode dulls the throttle response and applies different programming to the ECU to reduce torque and power output - it just makes the engine a bit more docile and the brakes less aggressive to make the car react less to knee-jerk violent foot movements when you s**t yourself as the car starts to slide or go the wrong way. It is up to you if you think you can do better without it - but you are probably wrong.
I am most definately not confusing TRC with the rev limiter, you don't even know the difference between the traction control and snow mode FFS.
Neither of them have got any thing to do with the brakes either.
And finally I am not wrong I HAVE BEEN THERE, FOR ABOUT THE THIRD TIME OF SAYING IN THIS THREAD. The traction control kills the engine stone dead if you keep it cut in, end of. If you know better go out and try it for yourself and learn what you are talking about before you post up.
Oh and the quote you have above is not from me.
