Quick Overview


* Required Fields



“There is no such thing as too much power!”.  That being said, OE Tuning’s Stage 1 ECU tuning package for M278 4.7L biturbo gasoline V-8 is just the answer for Mercedes Benz S550 (also known as W222 S500 outside USA).

The Mercedes Benz M278 power-train is a monster after tuning that rivals performance of a stock 63AMG 5.5L bi-turbo. When compared during a side-by-side comparison on the street, the OE Tuning tuned S550 has performance slightly better than a S63 AMG biturbo. Performance gains as seen on the dyno are +110-130wTq & 100-110wHp to the wheels!



Features of the tune include:

-      Increased Performance and Driveability

-      Higher Torque request for TCU

-      Speed limiter removal
