Best 330i Performance Mods?

What's the best way to add a little more pop to an '06 330i? I don't find any well-reviewed chips or software upgrades. I've been reading about the various intakes people around here are using. What else might add a few hp and ft/lbs? FYI, I'm not looking for "sound upgrades", just performance. Thanks!
