Youre doing fine...I'm lucky to get 14.9 in atown of 50K after moving from a city of %+million. in fact before I put the K&N on it, I was at12.9-13.1 under 50 mph, average 30mph driven. I did install the 44 muffler from Flowmaster and not sure if that did anything, but it sounds Great!.
Have fun and and stay Safe!
