"The Gas Saving Switch"

Found another one today. It claims to cut your fuel use by 5.5 gallons from every 10 gallons. So, a 55% (or is that 110%) increase in fuel economy, by some device you plug into your OBD port? Right....

I highly doubt anything you plug into your vehicle OBD port will increase your fuel economy by even 50% in only 30 minutes. Even if you could adjust your fuel mixture to full lean (i.e. 16:1), you’d only get about 20%.
I did some searches, but that turned up the original video linked site, and some "reviews" that were a verbatim copy of the original site text, with some picture variations.
