I have only 40+ miles since the update but a quick assessment "feels" like there is less forward lurch when the engine is decelerating. Let off the throttle and there is a smoother transition to coasting. Very noticeable RPM hesitation at ~1400rpm. I had some slack removed from the throttle and this is also contributing to a much more responsive on-off-on throttling feeling. Top this off with the first oil change using synthetic oil and even the shifting is easier/quieter. All of this with a great big grin from ear to ear until the low oil light came on. Everything just feels smoother. Maybe it's my imagination but that's OK.
