The VNT certainly explains the increase in torque down low.........but, it doesn't explain the falloff in torque from 2350 onward. It's my understanding that the VNT functions like a very small turbo at low rpm's and then, with its vanes open, functions nearly identical to the stock turbo at higher rpm's.
