So I may be insane, but I have a WW IX and my friend has a black IX.
Similar mileage. Both 5 speeds.

When I drive, say in 2nd or 3rd gear and let off the gas I feel much more forceful and sometimes jolting engine braking whereas if I drive my friend's car it has much more of a coast to it.

Does this have to do with any sort of tuning? It's not high RPM stuff. It's lower RPM around-town driving sort of things.

My car likes to buck a lot more than his.

Thoughts?
