just purchased a slightly used 2013 A6 prestige.

having the APR tuning and the supercharger pulley & belt upgrade done.

Supposedly 100HP to the wheels. Anyone else do this yet on an older model?

 

I am looking at doing the APR Stage 2 with pulley upgrade as well. I have been searching around many forums and have not been able to find out any opinions from owners. The 3.0T tune just came out not to long ago. I am hoping people will start getting them done and start giving their reviews on the forum. I would be interested in hearing your thoughts on the tune after driving a while with it.

 

Well picked up the car and from the limited amount of driving all I can say is ...WOW!!!!!!

Runs much better in sport mode. And can actually see slight MPG increase if you keep your foot out of it.

 

So it is definitely worth the money? I may have to start looking into it. Did you see much of a difference in Dynamic mode as well or just the Sport mode?

 

Have not yet. I have noticed that it is a lot more responsive in Sport mode and fuel economy improves in comfort mode.

I believe it's the best bang for the $$$$. 100 HP to the wheels. Check the APR site they have a sale going on right now.

The guys at Pure Motorsports in San Diego did mine. There is some labor involved you actually have to take off the nose of the car to get the pulley off. Very happy with the results.

If you have any specific questions I would call them or APR and ask.

 

Just a quick update. Got on the freeway set the CC to 75, reset the short trip computer and drove about 20 miles. In comfort mode I got 41.5 mpg average. pretty impressive. Will try some other different thing and report. Unfortunately I don't drive this car as much as I would like
