ya'll a bunch of soft cocks, why not get ya mum to drive it for ya while your at it
imho turn it all off, this is a challenge of you AND car against the track. Plus when i have left DTC on (one push of the button) the engine management is tooooo keen to cut power which again imho is much more dangerous than 'feeling' the car start to GO and change your driving style/line accordingly, after all isn't that the fun/challenge in getting it right?
Sure you have the chance of losing it, but if thats what your worried about don't go to the track.
