Solved: Traction control issue preventing acceleration at high speed

I haven't seen this covered in many threads but the issue is real.

Symptoms: TCS gets confused when going WOT at high speed (60+ MPH, 6th gear), thinks the rear wheels are slipping and starts cutting power.
This seems to affect older cars (mine is built 03/2017) and the problem gets worse with square tire setup (245/45/18 in my case).

Solution: update the DSC software (I went from 505 to 530). The updated software has much less intrusive stability control. Besides solving the above problem the car is way more fun to drive when DSC and TCS doesn't panic all the time.
