Rob, I am not sure if there is some learning in software in the vehicle, as I hear of such things. Gear shifts were a little rough to begin with but they have smoothed out. Fuel consumption has improved considerably. When we first got the car with standard tune around town we sat at 8.6L per 100. During various tunes, not in regen, we were up to 9.6. I reset the system with each tune to check. With your new tuning, tt is now sitting on 8.2L per 100. That is better than ever.
We retire next year and the car will be with us long term. While I have spent quite a bit to get to this point, my peace comes from knowing it will still be less than having to clean the intake system at some point having fouled from the EGR.
All the best for the holiday, Christmas and new year.
Kind Regards
Steve.
