I am really frustrated about this

The car is a 2010 Mondeo MK4 2.0 TDCi with the DW10C engine (one of the first with this engine.)
I have changes CCC via asbuilt, then I use the function "allow central configuration Data Parameter (CDP) Learning. (It says completede in 2 seconds)
Then i reset all adaptations.
BUT, the result is not there. The torque drop off is at 2800rpm, not 3400 as it should be with the 163 fuel map.
What can I do?
Regards Tommy
