a4 and m6
A4 = automatic 4 speed
In stock trim the M6 is better. Faster, better gas mileage, fun to drive, ect. Modded the A4 becomes better at drag racing. Better 60's, quicker ET's, less stress on the 10 bolt, more consistant, ect.
Congrats on the new ride. I think you're gonna have a lot of fun!
