The 06 up GM LLY & LBZ's have very few turbo problems, and they spool up very quickly.

Not VGT, but an alternative.

GM put the VVT turbo and LLY motors starting in 04.5. I have not heard of any problems with them. One of my buddies and his family have 3 04.5 all made with in 3 months of each other and haven't had any problems with them, and they are all EFILive tune to as much as you can get without upgrading the tranny.
