I'm not aware of a DSG tune for the RS5. It's already a tuned version of the DL501 transmission found in the S4/5. It's got faster hydraulics and more track tuned software. My first impression after driving the R8 was similar to yours. I felt the DSG in the R8 was significantly better, however, after a while I changed my opinion. They have different objectives. The difference is minimal if existing at all when both cars are driven hard. They shift about equally fast, crisp and hard when banging through a canyon road. The main difference comes more from having a glorious V10 making at least 100hp more than the RS5. On the downside, the R8 gets clunky at slow speed and city driving. It wants to be on the boil constantly, proactively downshifting even in D. It doesn't make for very smooth driving through the city. The RS5 on the other hand being a GT, does a better job in this environment. The transmission stays in a higher gear for more comfortable driving and starts smoother from a stop. So both have their advantages and disadvantages. I appreciate the more racy character of the DSG in the R8, because it's a super sport car after all and I don't daily drive one, nor would I ever wanna do a road trip in it whereas the RS5 is equally fun and shifts great driven hard, but it also calms down for just puttering around town or doing a road trip. The strength of both cars is very noticeable after doing a stint in the canyons in the R8 and then coming back, roughing it through town and then change into the RS5. It's quite obvious that the RS5 is a much better daily driver, but still fun in the canyons. It's tuned more versatile, IMO.
