The VG turbo makes that much of a difference?

If I removed the Vg turbo off my truck, I would drop from 9 mpg down to high 6's. All my low-rent profits would be gone, might as well go work at a fast food restaurant, i'd make more money.lol

Just found your article on VG turbos. So now the question, can one be added to a cm570 without an egr? Or maybe more precisely, is there an ECM profile to take advantage of the non egr VG for efficiency?
