RENNtech boosts V8-550 BiTurbo Series to new Heights
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 550 gains up to 138 HP and 262 LB-FT. This Software update delivers up to 10 HP and 99 LB-FT more than the previous version.
The vast amount of increased torque across the entire RPM range gives the 550 an extra edge to compete with AMG powered vehicles. All this without sacrificing around town comfort and daily driver reliability.
The M278 550 engine is currently offered for the W222 S Class, C217 S Coupι/Cabriolet, C207 E Coupι/Cabriolet, C218 CLS Class, X166 GLS SUV and R231 SL Class.
The updated RENNtech software will also be shipped for the discontinued models, the W221 S Class, W212 E Class, C216 CL Class, W166 ML Class and X166 GL Class.
In addition to the updated ECU Upgrade, RENNtech is releasing the all new RENNtech 550 Sport Package. Included in this all-around transformation package are ECU-Upgrade, Carbon-Fiber Decklid Spoiler and Stainless Steel Sport Mufflers. Optional are your choice of RENNtech Deep Monolite Wheels in Brushed Aluminum or Gunmetal. Currently available for select models.
