Hi, I've just had my 2017 2.0d 177 bhp XE auto remapped/carbon cleaned and my findings are as follows: oh and yes, I know it's not an XF but thought this may add value to someones decision making.
1.Engine is definately quieter on start up and idling especially when cold.
2. Gearbox shifts only slightly quicker however the low speed lag appears to be significantly lessened if not totally diminished.
3. The 210 bhp and 490Nm torque appears well suited to the car, which in my opinion is under tuned by around 40-50bhp.
4. Driving in dynamic mode and or S, lowers the 0-60 mph around 7.0 secs from 7.6 secs.
Overall pretty positive and I believe as long as I don't drive like I've stolen her, longevity of parts such as turbo, clutch, transmission shouldn't significantly age prematurely.
All in all a smoother more comfortable drive but not enough power to throw you back into the seat,
Hope this helps.
