Here's an easy, but not necessarily cheap, mod to get you about 15 - 20 additional ponies on the dyno: ExtrudeHone.
You'll need to send in your intake, so this may not be ideal for those without additional transportation options, unless you pick up an extra intake from eBay or a salvage/junk yard. But it is a proven and effective performance increase.
If 6 or more are interested we can get a Group Buy on this as well. You can count me as number 1!
