Can you tell if S5 has uprated supercharger pulleys?

I had my car flashed to stock today.

I've had issues with the cats since buying the car so wanted to see what a stock flash revealed.

Turns out they are both buggered.

I'm trying to work out if the pulleys have been changed. As I've been told I could be causing damage if so on a standard flash.

There is a metalic buzzing on throttle since the standard flash.

I just measured it and it's about 68mm top to bottom
Standard pulley diameter at the belt should be 63.25mm
