EPA doesn't test coasting in neutral, so that's not why autos sometimes do better on the EPA cycle.
Real world, manuals still beat autos.
Besides, you need to be at 2000rpm before gliding in gear to enter DFCO and use zero fuel. This isn't very useful in an FJ but works brilliantly in small cars. You can also key off with the car in gear, this keeps everything working but essentially means forced DFCO.
