http://cgi.ebay.com/ebaymotors...&rd=1Check this out. Sounds very similar to all the other +20 HP 'chips' and 'resistors' on Ebay. What do you guys think?

It appears to work by tricking the ECM into thinking the air is much colder and so providing more spark advance and fuel. Even if it does work to a small degree, it's likely just a variable resistor, available for ~$3 from Radio Shack...
