A number of cars have gapped down. Maybe you should...

At this point the JLR dealer should put the computer on the engine and make adjustments that are not in the parameters of the ignition and timing. If you have a connection at a Ford dealership, their terminal may be able to cope with it, or a quality well equipped independent shop. I have a feeling the problem will pop up quickly.
