Up for sale is a Chipwerke Pro I had on my 2015 B8.5 S4 for only a few months. It will work with the supercharged 3.0 V6, including the Q5, A6, S5, and S4. You can read all about it on the forums, but this definitely produces noticeable gains, especially beyond 3500rpm. The only reason I am selling is because I have been taking my S4 to the track and I need the redline raised from 6500 to 7200 that a full flash gives, since I am bumping the limiter at several points on the track. The B8.5 manuals are unfortunately limited to 6500 which is fine for the street since this motor makes max power around 5500rpm, but when you have to finish a straight or continue accelerating just before braking on the track, you don't want to upshift and then have to do a double downshift. Asking $320 shipped, I bought it for $450.
Everything works perfectly and includes the box, module, and the harness. It only takes 30 seconds to a minute to completely install. Please PM me if interested, I also have photos, but I don't see a way to attach them to the thread.
