I see you added an air/fuel meter- I had one of those on an old Cougar of mine, and because it tapped the one-and-only O2 sensor on that car, it screwed with the mixture and made the mileage horrible.

Just something to watch for, unless you added a bung for a separate O2 sensor (or they have improved monitoring technology since then). Mine was just a scotch-lock that crimped onto the O2 sensor wire (which I imagine added a parallel load and screwed up its readings into the ECM).
