Mid 13's at idle is fine as that translates to ~3% CO. Cruise is where you pick up the mileage of course and mid-14's seem to work best. Boost is like 5-6 mpg in the high 11's:1 so that is probably what you are getting! I find myself driving the car at higher RPM's to hear that tuned song, really sounds cool.
