My 2.7 xf from new always hesitated when moving off from road junctions. I had it remapped, I am not a speed merchant, instantly it was more responsive. I also get more mpg, I tow a caravan the torque has definitely improved. When I asked at the jaguar specialist who did the remap why didn’t Jaguar do it . The suggestion was why should they when the 3 litre was replacing the 2.7.
