2009 Carrera S. 23.7 mpg consistantly according to the on-board computer. That includes brisk open road driving and stop and go driving in and around town. Car is just over 5K miles old.
(EDIT) sorry didn't notice what you were driving now; Congratulations!! Your mpg with the PDK will probably be a little better than mine.

'09 C2S 6MT-First day I owned it I put 1100 highway miles on it and getting 22mpg at 85 mph.
It now has 4500 miles on it and the milage has improved to 23.5 mpg, more or less.
It's the most fuel efficient auto I own.

2009 C2S PDK, with a bit over 3000 miles. Overall I'm averaging a bit over 23mpg (split about 3:1 highway:city). On a recent trip from DC to Norfolk, VA (around 200 miles) I managed a bit over 29mpg at an average speed of 72mph.

If you are relying on the PCM to track your mpg you may be in for a surprise. I recommend noting your mileage at your next fill up, then note how many gallons you put in, and then at your next fill, calculate total miles divided by the gallons you added last time, and do this for 3 or 4 fills. You may be in for a surprise.
In any case, with my 2005 SC'd 997 (includes larger fuel injectors) and 530HP I get about 14mpg in nostly stop and go. That's down from about 17mpg pre SC, so not too bad for the extra 175HP!
