I would think in your case 3.42 out of a 6spd Vette would do the trick. Once you start getting to 3.73 and above in A4 car it gets a little buzzy on the freeway. Don't forget the gas mileage will suffer about 20%-30%. that could be up to 10 mpg difference.
I know this isn't about mileage but the .1 quicker in the quarter mile isn't worth it for a regularly driven street vehicle imo.

Difference between 3.14 and 3.90 3.14/3.90 = .805 or 80% 100-80% = 20% fuel penalty but really in the real world with double overdrive to be about 30% on those numbers. My experience multiple drives from SF to Palm Springs down Hwy 5 cruise control at 73mph = 28.5mpg with 3.73 vs 31.5mpg on 3.42 gears. That is only a 9% between gear ratio. The OP is looking at 20% or about 6mpg in his situation if he used cruise control everywhere. Most people don't. That is why I say 20-30% difference in gas mileage. Just math and a little experience.
Of course, this is just my opinion and lots of experience.

Difference .1 at the track 3.42 to 3.73 ... 13.10 vs 13.00 temp ~ 70-80 degrees both times.
