I have to believe that the Polestar tune would improve the mpg... maybe you need to up the state of tune to stage II ?? Or maybe the other tuner we were discussing earlier in the thread. Of course the byproduct of this would be another 50bhp, but you'd need less revs to get the same speed on the motorway and thus better mpg. That's why it is important to have the most powerful engine you can get so you don't need to rev it too much :-)

I'd use exactly the same amount of revs on the motorway for the same speed.
The other owner on the thread has a polestar map, he's getting exactly the same mpg. Which is exactly the same as the d6.
