Our proprietary ECU upgrade for the Mercedes M278 Biturbo engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.

With the newest update of their Software Upgrade for the M278 – 4.7L V8 BiTurbo, RENNtech boosts the 550-Series to AMG Power Levels. The RENNtech upgraded M278 now produces 540 HP and 705 LB-FT at crank.

Compared to power numbers by Mercedes-Benz, the ML 550 gains up to 66 HP and 139 LB-FT. This Software update delivers up to 10 HP and 99 LB-FT more than the previous version.
