Kev, have you had a larger Throttle Body on the DNA Stage 3 Airbox?

The collar between the TB, and the rubber hose connecting the conical air filter will need boring methinks. But I may get a new one knocked up, if there isn't enough material left on the collar.

I have but not on the dyno, you have to get it machined out to match the bored throttle body.
