Has anyone had any experience with putting in a computer chip to improve fuel economy. I have a 1999 Ford f350 Diesel Dually and get 14 mpg around town and 18 mpg @ 60 mph on the highway. I was told I could get better with a chip. But I don't know which ones are good ones. They are to expensive to experiment with.
