I know ford have pointed out and said its possibly a egr fault (which you can clearly see in the live data the erratic change) but I'm 99% sure you have the dreaded throttle position problem, have you measured the throttle position from 1% to 100% at both ends(pedal and body)

I would have happily helped and put my input on writing but your miles away from me

It's quite bad that ford won't attempt to help being as its not that old
