I would like to open a thread on the various companies that offer tuning for the 2016 S8.
One of the important factors here is that I live in a place where it is impossible to take it to a shop to have the car flashed, so of great importance to me is the ability to be able to flash the ECU back to stock when the car needs to go to the dealer for service.
Obviously I would like my S8 to be the fastest beast on the road, but I also want it to remain reliable.
I am also curious about the stage I vs stage II offerings and the added benefit vs cost of going to stage II.
As I look around it seems that there are several companies that have great reputations, APR, GIAC, REVO, EPL, MTM,
What are your experiences, opinions or recommendations?
