Default gas mileage with 3.42's

I will most likely be doing this pretty soon and wondering how much the gas mileage goes up in the city. since most of my driving is city I am hoping my overall gas mileage will go up from my 2.73's. right now I get about 15 city and 20 highway.

I did try to search for this but so many threads came up that just have 3.42 in the sig's, I decided to just go ahead and ask

You're going to lose a couple MPG in the city w/342's - only 20 MPG highway seems low w/2.73's.

You're going to gain a couple mpg in the city w/3.42s- more mechanical advantage.

IMO, if you're getting 20mpg with 2.73's tehn you have some other problem. Tune maybe? I'm an M6 guy, but I know A4's aren't that bad on the highway.

I need to go out and check the mileage again. but yea I think it is about that. Im thinking of sea foaming her to get some more mpg. I thought I would gain a couple in the city with the 3.42's. hopefully that will help out as well
