Tune needed for accufab throttle body?

[Schmity]

Was told by MPT i would not need a tune update for an accufab 84.5 mm throttle body. The car is already tuned with a boss 302 manifold and steeda 101mm CAI. I was under the impression that to get optimal hp gain from this piece that changes must be made to the tune to accommodate the new throttle body.

I doubt it requires tune changes. I swapped mine without changes and the car ran flawlessly. If airflow increases the MAF would do its job so what else would be needed.
