What kind of driving are you doing as well? I routinely see 18-19 mpg when I don't drive on the interstate for a week or two. If you have a relatively short commute to work, don't spend much time on the highway, and/or your car doesn't get much time to warm up, the mileage you're seeing seems totally reasonable.
I have never understood why people buy this car with 250-300 hp (depending on model year and tune) and are then surprised it gets similar gas mileage to that of a V8 of approximately the same model year putting down similar power.
