chips for '00 XE 3.3L?

I am looking for a way top increase performance on my '00 xterra. I just finished searching the site, and all I have found is a reference to www.jetchip.com.
Does anyone know of anything else that's available?

Thanks.

Nope, ain't nothin unless you dig up Olegka's posts about the "rice shop" that he found in Jersey or thereabouts that supposedly tweaked his for him.

I bought my 2002 X SE used about 8 months ago. I bought it stock. So far I have put in an Eclipse AVN2454 CD/DVD/MP3/Navigation head unit. I am also working on the rest of the sound system install. I also want to do some performance mods and here are some links that I have found for aftermarket performance parts. Most are intakes and exhaust.
