Not bad work when a 15 second OBD upgrade costs £1200

I missed that on my little phone screen.... Surely the arb and bigger brake upgrade isn't entirely nessesary as the S cars have bigger brakes anyway....?
The previous owner of my C63 spent 1200 on a software upgrade but that included the auto transmission as well.
I wouldn't say it feels any different to the last C63 I had though....
