Actually, I think that there is still some traction control on, even when you turn off VCD. I have noticed at the track that, although I have a lot more freedom to wiggle the back end, there have been a few moments where power was momentarily cut. It seemed to happen coming out of the same turn each time and I suspect that I was hitting a slightly uneven surface, bringing one wheel off the ground for a moment. It's not enough of an un-level surface to have an effect on exiting the corner, but the car reads a sudden extreme difference in wheel speed and compensates. Unfortunately, instead of just cutting power to that particular wheel, it drops my RPM limit for about 2 seconds (feels just like limp mode, except that oil temp is not the issue). Power is quickly restored and I just end up losing a little time.

It was very reproducible for me, depending on how fast I tried to exit the corner. The frustrating thing was that the issue was happening after I had wound out the wheel and was going almost completely straight, so the wheel skip has no negative effect on my handling. Very intrusive, in this case.
