Even though it has a huge 6.3L V8 engine and between 457 and 487 bhp, for some C63 AMG (204) owners this is not enough. Litchfield are happy to bring their power level up to that of the DR520 limited edition and we are also able to tune the 507 and Black Series variants.
We are able to fully OBD custom remap the C63 AMG (204) standard ecu. This will lift power by 40 bhp on a standard car and 60 bhp on a car with the Milltek downpipes and secondary decat pipes fitted.
The graph to the right is a remap on a car fitted with the Milltek Downpipes and decat exhaust parts. As standard this demo car made 450.1 bhp and 417.3 lbft, so a little lower than Mercedes' stated figures.
Milltek Sport offer secondary CAT delete exhaust options for the C63 AMG (204). This is a simple, very cost effective secondary decat, giving a slight power increase and more sound on full throttle. The power and torque increase is over the entire rev range without the sound becoming intrusive into the cabin. This option will retain the standard Mercedes rear exhaust system and fit all models. The secondary decat pipes take around an hour to fit and works superbly with our remap to produce over 500bhp.
