Does anyone here have the Polestar tune on a T6, and use it for towing? I just purchased a 2019 T6 (dealer swap, so the car won't arrive until next week) and am considering having the dealer add the Polestar tune prior to delivery. I'll be towing an enclosed trailer with small car, total weight about 4000 lbs. Based on Polestar's claims, it seems like it should help when towing -- a bit more mid-range torque, quicker downshifts, and holding lower gears a bit longer. Anyone have some real-world experience to confirm this?
