that's pretty funny...I guess those testimonials on the eagle research site are make believe too? I am actually getting the khaos gas saver on saturday so I will let you know how foolish, or wise I am on this. They have some pretty impressive results including test results.
Is this the device you ordered?

One common complaint us skeptics have when many of the fuel savings testimonials are done is they are not installed as the only change in the engine. Many older cars that have such devices also get a much needed tune up, replacing plugs, etc, at the same time. If you want to have a valid comparison, make installing this device the only change you make. Then, by all means, get back to us after 5 tank fill-ups with results.
