Hello, after a long time of thinking, I decided to give the Xc90 a few more Ps. After my Volvodealer’s tip, I decided to do a tuning with which the control unit was simply reprogrammed? Unfortunately, I have no idea how it worked exactly, but took less than 20min. After I was on the road with it over 2500km, I can say that the Xc90 is much better on the gas. That, I call it getting deep air b The speed limit was probably deleted at the same time as I did not drive the car yet. The highest was so far 190km/h speedometer, which was achieved with less “start” than before and one had the impression that there was still something to come. Most clearly one notices the extra power when accelerating out of construction sites. To the consumption I can say that the so far significantly decreased, would almost say that at the moment I consume 1l less. So far there have been no faults. Greetings Patrick
