What other mods do you have that requires a bigger throttle body? The stocker usually flows pretty well for awhile.

A. A bigger throttle body at this juncture is a waste and B. you'd need a re-tune for the transmission with it (assuming you already have a tune for the cam swap).

The change in TPS voltages will affect your shift points slightly.
