I hit the loud pedal hard to turn out of a junction and it came on briefly as the back slid and it corrected itself. I personally feel the TC is spot on, it never intrudes even driving quite quickly. My old 200sx tuned to 250hp with no TC would weave all over the place, I wished at the time this had TC. My last car a focus st running 290hp was like a disco, every time you accelerated it would make the TC come on, but I guess this is down to FWD as apposed to RWD.
