Two words: Holy crap!
@kennethnilsen69 This was awesome
I just got the box and tried Light tuning mode. I forgot it was -12 celsius outside, forgot my gloves and scarf and drove to work to test the difference. I did 108 downhill and had no problems keeping 75+ uphill in a tunnel where I was previously not able to do more than 60-62 km/h. But the biggest difference was the response and the acceleration. That was just incredible. It's really icy today, and I had so much fun.
The only thing I need to do something about is the regeneration. I felt it kicked in much harder now than before, and it actually caused the back wheels to lock on a couple occations on the ice. It was fine when I got used to it, but I still want to adjust that.
Going to try Medium tuning tomorrow
