You sure about that? I'll bet the intake runners or even the head are still more of a restriction.
With the bigger throttle plate it'll feel more responsive because you're getting more air at smaller throttle openings (unless you remap the throttle curve), I'd be shocked if it actually makes a significant amount more power (even boosted) over the stock one unless you replace the intake manifold and open up the head (and cams).
I'd compare a log of the raw MAF reading before and after the swap to see if it's actually flowing more air at WOT or not. It doesn't matter if the TB flows more air, if it can't get into the combustion chamber it'll still be backed up before the TB.
