SCT on DJ's Economy and a 4" straight pipe. I get about 20 miles per Canadian gallon. An american gallon is smaller so a little less than that for you americans.

Edge Evolution 2 on Extreme tune driving normal, my first tank 80% hiway 20% city traffic. My milage is up a little over 2MPG. Got 18.2 on this tank. Usually I am 15.5 - 16 on same driving conditions. It does OD on grades that in the past shifted to 4th. That seemed to help a lot.
