FYI, you can get the AEM for about $1400 new (my friend bought one brand new off Ebay for $1k). but Hondata is still cheaper. Also unless you want to buy a laptop, you're limited in what you can do anyway, so Hondata is better there too. I realize Hondata requires a laptop, but my point is that unless you've got a laptop you can leave plugged in constantly, you're just going to be changing basic stuff, which the Hondata will do wonderfully.

Oh, and 22 psi should be possible, but it will be mostly heat. Some of the 2.3 Turbo guys run 25 psi, and they make more power, but inlet temps sure are warm then.
