Step one on a W212 E63 AMG is not the tune. It's two engine mounts and an MCT service. The 2010-2011 car is the M156 6.2 naturally aspirated V8 at 518 horsepower; 2012 up is the M157 5.5 biturbo — 550 with the Performance Package, 577 in the facelift S. Build order: platform, then ECU and TCU together, then heat, then tires and brakes. Send this to the guy who flashed his E63 in week one.
