I get about the same as Kenny with a full RS2/Pastore set-up. I mostly drive highway miles going 65 miles each way to work. At 65-7 mph I'll average at the higher end of the 20's close to 30 mpg, at 80+ mph it drops down to the lower 20's similar to around town driving and all of this is dependent on how much you love to feel the boost at any speed!
