I've pm'd unilevers but will also hit up gearhead, and see if they have or can recommend a tune to suit. I'm aware of the other options out there but as has been seen in the isx world some of the quality of these tunes is questionable at best...

Lastly certainly would keep the Vgt and would run a mile from anyone who suggested switching to a fixed geometry turbo in this application.

If all these so-called delete shops and custom tuning guys can't even get an ISX right, it open as can be and nothing hidden, I doubt that they would fair any better with a different brand of engine. -- Just because you might have found some guys with that special screwdriver to tweak on one does not mean they have any idea how to use it properly.
