All gear heads have the same way of thinking….. “There is never enough power!”. That being said, this is why tuners offer packages like “Stage1″ or “Stage2″ for example. Mercedes Benz power-train “M278″ is a 4.7 liter twin-turbo (called “bi-turbo” by Mercedes Benz) monster after tuning. (The M278 power-train is named “550″ in the USA and “500″ in other parts of the world.) After installing the OE Tuning “Stage1″ ECU Tune the car tested picked up +110-130wTq & 100-110wHp to the wheels on the dyno above factory stock specs (dynograph displayed below) running premium pump fuel. When compared during a side-by-side comparison on the street the OE Tuning tuned CLS500 has performance slightly better than a CLS63 biturbo and equal to that of a CLS63 bitturbo with Performance Package.

We have Stage1 & Stage2 tuning packages to suit all Mercedes Benz Biturbo 500 & 550 with M278 powerplant. The M278 can be found in CL500 & CL550, E500 & E550, GL500 & GL550, S500 & S550 as well as SL500 & SL550 models. Please call to purcahse down-pipes.
