Anyway, when I needed to fill, the miles traveled (based on the tach) was about 250. So either one of three things happened here - either the numbers are correct, or the tune effects the reading on the tach, or I need to go back to school because I can't add!

So maybe the MPG for the Hahn is correct after all. Anyone else ever verified thier mileage with a Hahn turbo?

It is correct. Manual calculations have verified this on a number of installations.
