thanks for all the opinions guys..... 
I already bought 3.15 for ,I think good price and will pay the guy at the dealer to do it for $250 cash...for that money I'd rather wait at sturbucks than flat backing it most of the day.....
Will give my opinions next weekend.Also have diablo predetor so I'll adjust the mph shifting points....

3:15s v 3:42's
My a4 was equipped with 2:73. Had Chuck COW install 3:42'S and a2400 PRO TORQUE stall and never looked back. Chuck did an awesome job and actually picked up a mile or two per gallon. Performance is awesome. Go with the 42's and a COW tune and you'll be VEEEERRRYY Happy!!!!!!

Hold off on the hand held tuner. It' won't do much.
We've documented a few cars that drove a few thousand miles with the 3.42 rear and NO TUNE.
It will be fine as long as you don't go WOT....
Also, for those wanting to know.....
An A6 C6 with stock tires and a 3.42 rear will only be at 1,975 RPMs @ 70mph with the converter locked in 6th gear.

Well, sometimes after an upgrade to 3.42's, you will get trans slip codes and put the tranny in limp mode without a tune. Mine was doing that after driving on a couple hour road trip. so he MAY be able to go without a tune, and he may not, just depends on his vehicle.
also, the A6 c6 is quite a bit different animal than an a4 c5, but it's still not bad at 70-80mph on the c5.

What I mean is both-exhaust and the higher rpm's.
I do quite a few hwy miles and don't want to feel like in those high revving rice burners
If you look at the chart there is almost 500 rpm difference at any speed between 2.73 and 3.42.I usually cruise between 80-95 and don't wanna be in situation that it will start to be annoying,and I don't do track either ....just want to get off the light quicker......
