GIAC Software for the Simos 8.51 ECU in the B8.5 S4/S5 models is nearing completion!

^^^I would literally have to be in the C63 to believe this. Stage 2+ S4's aren't walking C63's (maybe barely beating) and they put down way more power to the wheels than these graphs and are lighter than an A7. it would take a whole lot more than a tune to get that big heavy sedan-hatchback to pull on a stock C63.

Heh, yeah when I read it I was like wtf? That's insane..especially with the A7 weighing 600 pounds more than the C63. Then again I'd refer to Auditude's post above..

Awesome tune. I run the tune on my B8 and the car is an animal. Very similar performance to Revo Stage 1 and APR Stage 2 V2.

It's tough to judge though since both cars are both automatic and that the C63 tried multiple methods (paddles, sport, etc.).
