Has anyone tried this performance chip to get better mileage on a Ford E450? http://www.gfchips.com/fordeconoline.aspx Comments?

fuel range on a tank was increased from 600 to 900 miles.
That's a 50% increase in gas mileage. Don't you think if Ford (or anyone else) could do that they'd jump all over it to increase their sales?
