Hello, (sorry for my English, I'm from Poland and I don't speak much) I have a problem with my Audi A5 (77000km), I have an overboost. There is no note in stock, but when I do chip tuning, I have a note - EPC. I changed the N75, DV and it's still the same. I will add logs and video as you can see when I accelerate in fourth gear 3k slows down. On Drive mod everything look pretty good.
