KOJO Tune Review
Woody did you ever figure up how much of a fuel economy difference you are getting with the new ecm? I just bought a 94 1 ton and if your mpg's has improved I might want to go ahead and upgrade.
my fuel economy went down because of winter diesel but its pretty much on par with last years winter diesel fuel economy. i get low to high 15's in the winter and in late april ill let you guys know what the summer diesel mpg will be. i would probably just keep the heath tune. probably not much difference
