most people like jim conforti's chip. i put an EAT chip in mine (http://www.dsylva-tech.ca/)
how much info do you want on chips? as far as general information goes, they typically only give you a few more horses but also smooth out your rpms, etc. some testimonials on the EAT chip claim that it even improves gas milage. i didn't have mine for long enough before chipping it to really tell you whether or not that's credible.
i've been satisfied with mine. it's a little bit peppier, which was about what i expected. as long as you don't expect HUGE things from a chip, you'll probably be pleased with either one.
