Hi, I've read the file from my Audi S4 2010 (CAKA, Simos 8.4) and compared to an original I got from the internet. It's definitely been tuned but I'm not experienced enough in petrol maps to tell whether it's a good tune - Is there anyone that would be willing to take a look and let me know if I send the tuned and original files over? The car drives very well and certainly doesn't lack power however when logged with VCDS the supercharger divert valve starts to open at high revs, I've been informed a good stage 1 tune should not divert/waste any boost at all, so it may not be optimal? If it's a bad map I'll have it redone, if it's OK but just diverting some of the boost at 6000+RPM I'll probably just leave it if it's doing no harm. Please let me know if you can help.
