This has been my question all along... looking at other testimonials given in the first post... including one wherein another said basically the same thing as you... that the gains stayed with the device turned off... and seeing their economy go from crappy to around average, I have been asking if the gains are simply due to the properties of water injection itself... which cleans out the engine and makes it run more efficiently.
The ignition advance helps a whole lot, too.
