Let’s examine one conspiracy theory. It is a popular held belief that “Special release” models are faster and for that you need to fork out another 50k, let's call it a “marketing ploy”.
What is it going to take for your C63 to go from being stock to achieving power produced by that of the “507 Special Edition”? ECU remap by Eurosurgeon is the answer! You didn't buy a C63 to drive it to PaK-n-Save and back, you got it to enjoy the chill inducing V8 rumble and to genuinely love the drive. So why not add another 55 Hp and 53 Nm to it?
