auto or manual transmission?

are you driving hard one day and then easy the next? If your getting on the throttle alot you will use more gas.

plus you put in a camshaft which isn't going to burn less fuel, and you bumped up to a 3.73 which is going to consume more fuel and have a custom tune which i am guessing is aimed towards performance(because of the cam), is going to consume more fuel as well. I went from a 3.42(M6 tranny) to 4.10s and my economy around town is like i have a hole in my gas tank, but on the highway i can still manage to get 25-28mpg

You may need to tweak your tune, I get better gas mileage than that with my mods.

Yeah I would check the tune, I get 22mpg in the highway anb 12mpg city with my mods. In average I get around 17mpg combined.
