Do you think this "Fuel Saver Module" is legit?

Hey guys I have been looking for something to help me get my MPG up and i stumbled on this and I really can't tell if this is legit what do you think?

Also I noticed my MPG has dropped from 19.8 to 18.5 and i was wondering would a dirty air filter cause this? Cause i need to replace mine asap...

If you're interested in saving fuel, what I've heard alot about is "improving your driving habits." The best way to do this is see what you're getting all the time for mileage with something like a Scan Guage. That way you can see what you're getting at different speeds, throttle settings etc. Unfortunately they are not money saving devices at $160 shipped.
