“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
- Improved throttle response
- Rpm and shifting limits can also be increased
