Well I can't wait. My X3 35i M with DHP was received in early February. The dealership convinced me to avoid driving in the Sport or + mode until I have 'broken in' the car ~ 1000 miles. Even said to avoid manual mode.
So, I've kept in Normal but definitely varied the rpm and speeds. The other point from the dealership (which I think is valid) is one appreciates the sport handling and DHP if you've first grown accustom to the normal mode.
So, regardless, I'm just turning 1000 miles and look forward to enhanced performance this week!
