yep, 3.73.

I wish I could get that kinda milage! I usuallt get about 340 on a tank. But my last tank I got 12.5 mpg I towed about 5k lbs with that TC is the city....3000 stall+5000lbs+lots of hills= shitty driving truck an HORRIBLE milage lol.

Another reason why I usually get about 15mpg is b/c I have a heavy foot and their are lots of hills around here...unlike texas where it is prety much flat....you wont find that here other than at the drag strip and I get better milage there!

yup, you have 3.73s.

I had exact same tires and gears.

btw: no need to guess. use math :p

or if you're lazy, http://www.f-body.org/gears/
F-body A4's have the same trans as us and i'm 95% sure same gear ratios. enter your own tire size
