From my understanding, the turbo vanes adjust according to the engine in order to allow the turbo to spool up much faster than a traditional turbo. Basically, it gives you almost the feel of a supercharger off the line without robbing any power.

I think the variable part of the turbo is little vanes in a circle around the exhaust wheel. They are all connected to a ring that rotates via a solinoid. The ring moves under computer command. When you turn it one way the vanes point the exhaust flow right at the turbo wheel, creating a lot of boost at very low RPM. Turn them away and the exhaust is deflected, making the turbo much less efficient and controlling the boost pressure. And anywhere in between depending on engine load, RPM, etc. It's a very much more efficient way than using a wastegate. I wish my 7.3 was equipped with it.

I don't know how it works - but I just drove my Dad's 6.0 today....
His truck is making some serious turbo whine way down low in the RPM range where my 7.3 is just thinking about starting to spool up. I haven't convinced him to get gauges yet so I don't know how much but it sure whines an awful lot - it's almost annoying. That's the whole point of the new VV turbo - it can boost quick down low and still give you great top end response.
