I trust they had it super hot? That helps but probably won't be enough, to be honest those figures point to a Lambda probe failure. The other thing that might be worth considering is the fuel pressure regulator, not sure if you know but the amount of fuel injected is a combination of the injector pulse duration and fuel pressure in the rail, one overlooked area is a faulty pressure regulator. There is a schrader valve for checking the line pressure and any decent garage should be able to check for you, sorry but don't know the Ford figure but reference to one of their dealers should be able to quote the figure. The adaptive shift will try and adjust the pulse width of the injectors until it reaches its pre set limit then it will pop a MIL light on and store a code.
