In an NA motor, I'd think that you could keep AVCS active all the way to redline and still have gains, where as under boost there's the blow thru potential that Phil is talking about.

Thats good info. I was thinking the difference would actually be a bit more useful with an NA application, but wasnt sure. I really hope there is more work with this in the future.
