I searched and didn't find this discussed before. I am looking at a 2011 A5 and my A4 is APR stage 2 plus. I will return the car to stock and sell the hardware items buts its a no go on be able to do anyhting with the software which just sucks. Why is apr not selling some kind of software loader where we can return the car to stock and atleast sell or upload a new software file to the loader. I have owned and currently own a diesel truck and they sell the loader and let you change software at anytime you buy a new truck same brand or different brand if they write the software. The loader is about a 1000 dollars with gauges but its worth it with the flexability. (H&S performance) So who makes a good tune and actually sells the loader where you have options. At this time I have no plans to go back to APR. I know of the Swedish tuner BSR who I might give a try.

Thanks
