No difference without it being mapped, other than it might not work properly as the ECU will be thinking it's a standard size and opening it as wide as it would the OEM due to the throttle being DBW.
The stock TB is good for OEM cams to be honest, any gains at all on a bigger throttle body are minimal but if you're getting a larger bore inlet manifold it does make sense to match the TB to it.
