The tuning box compensates for the lack of engine power of my VW Polo 2.0 GTI 200 hp, especially at high rpm. I now have the real GTI feeling! I was a little worried that the box would disrupt the operation of the DSG gearbox, but it's fine. On the other hand, I don't see a significant decrease in consumption, but it's true that I drive hard…
