3.73 gas mileage?

[jakef777]

I was thinking about doing some 3.73's. I have 3.23's right now. My car is also a a4. How big of a gas mileage difference is it? Most of my driving is done on the hwy. Also, what kinda of performance upgrade am I looking at, like as in tenths of a second? I want to do a stall but I think i want to do something that is less harsh on the trasmission. So I just thought I would do gears. I would really appreciate any opinions!

You can compare highway speed RPMs at www.f-body.org/gears/ Don't think you'll lose much, I went from 2.73 to 3.42's and a stall - only lost a little on the highway.
