Look. I'm really happy all you guys think your raising the MPG you get with your cruiser with what you believe is a miracle device.
Has anyone heard of the CAFE standards that all the vehicle manufacturers are clambering to achieve? If it was that easy to throw in a hunk of metal with a hole it in (that whistles) to better the overall MPG of the fleet, don't you think the manufactures would have jumped on it.
They are just about to implement the toughest CAFE standards that's ever been established which will put an end (or a drastic slowdown) to a lot of the big V8 performance cars that we know and love.
Anything that would boost the CAFE measurements by a couple miles to the gallon would be a life saver to the industry.
