Look on your door panel for your list of codes.
GU3 = 2.73
GU5 = 3.23
Generally speaking the SS and WS6's had the better gear by default but the Formulas and Z28's could have it as an option.
With my car (3.23) I turn 1500 @ 50mph with a stock diameter tire.
Speed (in mph) at 2000 rpm for an A4 by rear gear, assuming stock tire size and no PWM slip:
2.73: 79
3.23: 67
3.42: 63
3.73: 58
4.10: 53
Throw in a little PWM slip and 62 mph at 2000 is dead on for 3.42s. Probably switched gears by the previous owner.
