Ok, getting closer to my goal of a tank-avg 15 mpg in the winter time.

Got 14.0 mpg on the entirety of my last tank. Not so awful. With a few more aero-mods, and an ECU tune, I think I can make it pretty easily. Though with a possible early spring season right around the corner, I may not truly find out until next winter as I'm not quite ready for any more mods just yet.

I can hit 15+ mpg easily on individual trips. But any short trips around town really kill the mileage. Same for days like today... 5 degrees this morning. The engine heaters can only do so much while parked out in the wind.... basically a cold start still.
