I have a 2013 A6. Has anyone had the APR tune done to their A6; the ECU tune and the supercharger pulley? Was wondering whether anyone experienced anything negative about this combo tune. Perhaps engine issues or tranny issues. Maybe you could comment on your take on the resultant performance.

 

Hey there, I have a 2012 A6 Prestige and got the stage 1 APR tune. No problems whatsoever. I took it to reputable place in Denver to have it done. The power gained is pretty noticible especially from a stand still. I love the way it performs now. I am doing the stage 2 and pulleys in the spring and then will do the ultra charger kit in the summer.
