After you get used to Sport+, don't be afraid of "Track" mode on the street where safe to do so. Noticeable increase in responsiveness and brutality of acceleration.
My only problem with Sport+ is that it never fully "relaxes" when cruising and, after a quick squirt of speed, it holds the low gear for too long. I find myself feeling bad for the car working too hard and twisting up from Sport to Sport+ for a quick burst and then twisting back down to Sport when I finish my safe and legal passing maneuver. :smile:
I wish Sport+ were just as eager on the throttle mapping and downshifts, but still cruised in 9th gear and reverted to "mellow mode" faster after bursts of speed.
