It's not FI, but I can get 30+mpg@55mph in a 3000lb truck with the drag coefficient of a brick and no OD. It sounds to me like the carb is running way, way rich. The nice thing about the carbs w/ the oxygen sensors is they'll always run at stoich during cruise, since the oxygen sensor controls fuel flow.
