I've had this battle myself, as probably most have that use fuel controllers. I normally start getting my fuel light around 125 miles or so with almost all city driving. I've had it drop as low as 110. One aspect of owning a fuel controller is that you're most likely going to richen your air to fuel ratio over the factory settings. The trick is balancing your performance against fuel economy. I'm not personally familiar with the Lloyd's unit, but what seemed to make the most difference on mine in terms of getting better mileage was deferring to the factory settings for idle and 0% throttle settings and being a bit more lean at low rpm and low throttle positions. That still gave me the power I was looking for without paying too big a price on mileage.
