Nice writeup. Owned two DSG cars myself ('05 New Beetle TDI and '08 R32) and have spent significant time behind the wheel of an APR-tuned '07 GTI DSG, so I consider myself very familiar with the transmission and have collectively put well over 100,000 miles on a DSG. The TDI DSG seemed to respond best in Drive, but I drove my R32 in Tiptronic mode 100% of the time. Only other tip I could add is that when slowing down, downshift accordingly. Don't wait until you need to reaccelerate to request a downshift. Yes, the method described above helps alleviate any pauses in acceleration, but if you're downshifting as you slow, you'll already have the appropriate gear for re-accelerating. I'm very much looking forward to picking up my '13 Hybrid SEL Premium this week and getting familiar with the 7-speed DSG in that car.
