It can be ****** dangerous (and scary) when you encounter a situation where you need full acceleration capability, and the computer "decides" you don't need any throttle after all, despite the fact that your Loud Pedal is fully depressed ! 
Overall, there is no doubt that VDC is a good thing and keeps most of us out of trouble (maybe saving our cars from ourselves, in some cases), but the straight line acceleration thing I don't understand. With VDC off, I get anything from a slight chirp and fishtail squirm when I hit 2nd at WOT, all the way to a back end "jump" sideways of a few inches (just like the old muscle cars) and with VDC on, I've gotta short shift it (at 5,000-5,500 RPM) to keep the VDC "nanny" from taking over.
Last night, after reading this post, I drove around a little with VDC off, and this car is definitely very easy to get the back end to step out and rotate on you, but just as easy to cross up full throttle and get straight again (if you're in the correct gear) - it's all very dramatic, I must say, and will probably result in disaster sooner or later, for a novice like me.
So yeah, leave it on, unless you need full acceleration in a straight line, then, ........

Valid points there. I too have hit the 2nd gear bog at times, and even in 3rd, and I agree that in some circumstances that can be dangerous too (e.g. when attempting to merge). At first my post said 99.9% but I changed it to 99% for just that reason.
The way I have learnt to deal with this is to just be smooth on the 1-2 upshift. VDC will allow a little chirp of the tires without cutting power back, and I think that's about all I need for max acceleration for all practical purposes. I can still shift at 6500 rpm, I'm just careful about how I squeeze in the gas as I engage the clutch in 2nd. I would have to agree that if you're drag racing (ON THE TRACK) or trying to do an instrumented 0-60 run for Car & Driver or something (neither of which I do), then yeah, VDC off. I would probably also turn it off for a lapping session at Barber Motorsports Park. But for the street, I leave it on. This car is plenty fast without going into controlled wheelspin territory. In fact, there have been a couple times where this car has taught me I'm not as good a driver as I thought I was. So, my VDC stays on.

I second you on the "not as good a driver as I thought I was" comment. Every now and then, when pushed too hard, a car like this will break loose and then it says "OK - showed you what I can do - now, let's see how good a driver you are, Mario".
The last time this happened to me in a serious way, I've come to fondly recall as "The day I lost my Porsche (and bought a stranger a new fence)".
So yeah, leave the VDC on, guys

There's are times and places to turn VDC off, and have a little fun. But I'll admit it's saved me enough times in the short time I've had the car that I appreciate it more now than in the beginning. When I bought the car, I thought it took the fun out of driving. But after bailing me out of trouble a couple of times, I decided to be careful about turning it off.

Leave it on unless you have a specific need to turn it off.
Commuting to work, going to the store, just cruisin', especially in bad weather.. on.
Doing a little spirited driving on an empty road, or out at the track or autocross course... turn that thing off.
You should have a little experience in skid recovery, though. It won't do it for you when VDC is off, and the tail does like to swing out from time to time.

IMO, anyone who owns one of these cars should have a little experience in how to control oversteer because it you hang the tail out and get freaked and slam the brakes, you'll fully rotate.
