This past wednesday, ETG Bay Area programmed the all new 2012 Mercedes Benz C63 coupe. With just an ECU tune, we were able to achieve 83hp & 66lbs tq. (speed limiter removed, exhaust volume increase in 2nd and 3rd gear, hesitation/flatspots removed).

Yes, in order for us to reprogram your ECU, it must be shipped. Turnaround time is 24 hours given we receive the unit pre 10:30am delivery.
The tune is completely undetectable to factory diagnostics.

83 plus HP on a N/A tune? On a bone stock C63? No other upgrades? What do they do at the factory stick a banana in the tail pipe?
Did you upgrade the firmware on the trans also? I'm no MB expert, but that's a big torque upgrade for the stock trans. Whats the long term effects?
That thing must be some kind of fun to drive. Order some more back tires.
Man I miss my 09' C63.
