protium gas optimizer?

[honda_afford]

I was just looking for a good deal on a scan gauge II on ebay, and I found this bundle auction :http://cgi.ebay.com/ebaymotors/Proti...spagenameZWDVW
I searched on the forum and google, but didn't see any real reviews about it.

could it actually do something other than damage your car's system?

I guess if it does anything at all it would be on here already.

but the fact that they sell it with scan gauge is really dumb if it doesn't work because you would be able to actually see the results.

thanks
