Under 2000, you're just creating excessive wheelspin. The launch is hard after you spun for a couple seconds. But there's a slight cut in power before the pop.

I keep VDC in first to control wheelspin on launch. Then release vdc in second so power doesn't cut while upshifting so aggressively. Vcd will cut power the second a bump throws off the balance of the Z. I can control that on the wheel without cutting power. Hence VDC off.
