Hello together… I would be interested to know if it is worth having your control unit adapted in the sense of fuel saving – which is mostly accompanied by more possible power… I currently consume 5.8litres per 100km with my 2.0CDTi in the Insignia and drive every month in about 3000km… What do you think about how much the consumption would improve with corresponding “tuning”? My driving profile 90% AB and 5% rural road and 5% city. Speed… mostly about 100km/h in the 6th Ga ng… Is there even any experience value?
