New Audi owner here. Got a used 2011 A6 3.0T. I like the car and it drives well as it is, but I am also thinking about a possible upgrade. So, here we go. What are some of the available ECU upgrades for A6? What's the best in the market? Thanks!

 

Either APR or AWE released an upgrade for the S4 3.0T that's said to gain 100whp. It's probably useable in your car too.

 

Yea. I was on the APR website and also found someone who is going to do the APR updrade with pulley on his C6. That person said that APR will give you around 100hp gain where as Stasis and GIAC would give you around 75hp gain. Thanks for the info. I will take a look at AWE.

 

Oh man ....

I just found out I have an authorized APR installer 5 minutes from where I work. Will have to stop by and check things out. Anyone here had warraty issues afeter an upgrade? Voiding factory warranty would be my biggest concern.
