a bit hard to believe

Since I eaton swapped I noticed my fuel mileage really hasn't gone down which I thought was a bit unusual. Adding 135rwhp should do that, right?

I topped off the tank and ran it out until the fuel light came back on and then topped it off again at the same gas pump. It went 220 miles all city on just 12.66 gal. That's a city avg of 17.3 which is higher than my window sticker says (17 city, 26 hwy). I boosted ever so slightly many times during the tank, but no wot/full boost. I think I could get 18+ if I was actually trying.
