What I have found is that with the extra power you can drive up to your speed easier and maintain it with less throttle = better FE.

Similar experiences here.
Switching to an oversized TB sometimes brings drivability problems for street & road, however. Unless the OEM TB is clearly undersize for the application (rare), the TB is one of the last things I'd fiddle with in the intake system.
BTW any TB has some potential for improvement. Every bit helps:
