Cranky, it won't work unless you're running a piggy back to correct the MAF reading. You'll be running lean with a larger intake pipe.

Hmm, now I'm confused. What's the point of using a larger throttle body with the stock intake then? Can the stock tubes take advantage of a wider throttle opening without dramatically altering the air flow volume? I'm not opposed to running a piggyback, but wasn't planning on adding one prior to going FI.
