Stopped by dealer for recall of my wheel lug wrench (R73) on my '15 Trailhawk - Can't imagine there would be a recall on a lug wrench, but....
While there, they updated the following software modules: BCM, PCM, ESM, & TSM. I noticed the improvement immediately when I got on the road. Shifting is smoother and the transmission seems to hold in a lower gear longer. The Throttle seems to be more responsive and even the suspension seems a bit stiffer (maybe the BCM update - or just my imagination). In any event, I think this update "nailed it"

Does anyone have any idea what the internals of these updates really are? My dealer didn't have a clue.
