Maybe that is why you feel that the 2017 X5 may feel faster than 2014.

Thanks for the info. I was sure I could feel the difference between the two. That probably explains it!
I took that car today and absolutely thrashed it on a private road, of course. Got to 140mph and a number of times flooring it from 70 to 130mph. Kind of chickened out as I don't think my snow tires are really rated to go that high...
The car is very strong in that realm but in reality no one is going to drive like that on the street.
As Timberwolf mentioned, I would need to now take the tune off and run it for a hundred or so miles so the car remaps to the standard tune and compare what I feel.
