after retarding timing because knock was detected. That might be why you didn't detect anything. Plus I don't know if a Stock 2.7T would take advantage of anything over 95RON (91 Octane).

On my old car it was hours if not days before the ECU would adjust and forward the timing. I got really good at resetting the ECU but that had its own chalendges too since the ECU would have to relearn again.
