VNT control

[Dave]

You can run a vnt in quite a relaxed state which means you're not on the vane stops all the time, but you loose alot of response/spool down low. It would definitely have its advantages over a wastegate turbo, but you're going to loose 50% of the advantages a VNT will offer you over a standard wastegate turbo if you do run them in the relaxed state, but as said above to get the advantages of a vnt spool you need to run things hot/poor mpg/high emp/imp etc
