I have MSport + DHP and although my throttle changes between Sport and Comfort, I cannot sense any difference in the chassis. I've tried several times on different roads and just cannot feel any difference. I'm beginning to wonder if the electronic dampers are not working for some reason. I think I'll ask them to check (if they can) when I bring it in for it's first (early) oil change.
