Another tuner for Mercedes’ C63 AMG has jumped on the bandwagon with its version of a tuning kit for the C63 AMG. Calling its kit Stage 3, McChip replaces the AMG ECU with its own optimized ECU, as well as a Cargraphic exhaust system.
With these mods, the tuner claims that their Stage 3 C63 AMG now has
575 horsepower compared to AMG’s 451. Torque is also substantially
increased, from an already respectable 443 lb-ft to 510 lb-ft.
The tuner is mum about performance figures, except for saying that top
speed is now 193 mph. The tuning kit will set you back 14,000 USD and
you’ll have to leave the car with the tuner for three days.
McChip is also offering a 19-inch matte black wheel package shod with
Michelin tires, and these will set you back an additional 10,600
