I often turn my AC off when accelerating...don't know if it helps FE any, but it alleviates the double load whammy, so it theoretically should. Now that I've got a manual, I'm gonna try turning the AC on during engine braking.
Got numbers on idle fuel flow with AC on/off?
Always use recirc with AC or def...no sense bringing in more hot humid air.
