Well I have put nearly 500 miles on mine since being updated to the production version of the stage 2 DSG map.
S Mode is as unusable as ever (IMHO) but the revised D mode on the Stage 2 map is a vast improvement. The part throttle control is as before but full throttle mapping is slightly more aggressive and feels suited to the car.
It really makes the car feel faster, which just reminds me I really need to get some better brakes sorted
