Even when the AdvanceTrac is in sport mode it still seems to be pretty strict. I had it in sport mode earlier and was going WOT in 2nd. When I hammered into 3rd I got the car to kick sideways a bit and the nanny control engaged instantly. Turning AdvanceTrac off completely (press and hold brake pedal while holding traction control button for 5 seconds) gives you 100% complete free will to drive your car however you please. Just be careful!
