Lots of people will give you their opinions, personally I see no issues with 3.90's in a dd a4 / 4.10s in a dd m6. I wouldn't go any taller thou.

But at the end of the day it is what you are comfortable with,

Check this out and work out your preferences:

3:90 is a nice all around gear for the A4 & M6 trannys, max on the A4's and min. on the M6's for the street.
