If it was something monster powered you were after, Id be inclined to go to karl just cause that seems to particuarly excite him with the CVH and so it seems to be something that karl particuarly specialises in these days more than most other tuners who seem to be moving on more, but Im sure that the likes of MSD are still doing enough of them to keep their hand in for doing a setup on one even if they havent made quite such silly numbers out of them as Karl!
Lot to be said for having someone local too.
