The My06 stock intake tracts neck down to 2.5" for a reason that only some obscure GM engineers know. Most of the intake is 3". There's only a couple of aftermarket offerings and they all keep the neck so that recalibration isn't necessary. Is there any interest in a true 3" intake? I would sell these packaged with a free reflash, so it would be plug-n-play and you'd get a larger power increase than that from K&N.
Here's a shot from PROSPHOTO where you can see the silly necking:
