BTW, I get ~12-16 mpg around town, and ~22-26 mpg on the freeway. My mods are in my signature. Over an average tank of fuel, I usually get ~18-20 mpg.

You guys think by filling the tank only half way and driving will bump up the mpg slighty because of not having to carry that extra amount of gas around.

That's an old trick often used by us old guys.

I, too, have been getting ~12.5 mpg after the PFC. Once I leaned the map out a bit, I still have not noticed much different. BUT, it was ~11.3-11.7 mpg before PFC. I drive about 20% city and 80% highway, but 20% of the highway is Full Throttle. I don't really feel I gain any mpg when I just drive around...not boosting. But, on long highway, I know I'm doing much better by watching the fuel guage.

25-22 highway
11 in town.
Once the PFC was installed the around town driving drinks gas like it's going out of style. The stock ecu was tuned much better for this I averaged around 16.
