I just went from ~14mpg to 15 by changing out my dragging rear brakes

2004 screw 4x4 i replaced my plugs so far and get 13 mpg mostly city with a little highway. Running sct canned tune at this time. I drive it pretty easy but I do have an exhaust leak to repair and a stumble at idle when fully warmed up. Pretty sure i need new cops.
