I think the VVT means variable valve timing.

Also roll up to 3krpm and floor it - if it's a turbo, it accelerates
significantly better than the old one did. And I do mean clearly
significantly.

No, if a car has a broken turbo, it may do that. A good turbo can also
whistle on certain occasions, but not constantly.

No, if a car has significantly too big turbo and a crappy engine control
system, it lags 4 seconds with nothing happening.

Go ahead and give Saab 9-3 TTiD or BMW 123d a test-drive. They both have
*two* turbos, still no whistle nor mentionable lag.
