The test car was just to make sure the Evolve-R solution worked. The tune is the same one that they've been working on for a long time, see
here for details, notice it's at version 3.0. It's just that you used to have to take your car to VS Motorsport or to Evolve directly to get it (or ship the ECU). Now you can do it at home
Edit: Just noticed that page doesn't have a dyno. I asked evolve to see if they have any before/after dynos they can send over.
