ECU Upgrade - 26HP
Our intermediate level ECU upgrade for the Mercedes M278 engine still offers huge gains in performance across the entire RPM range, but with a slightly reduced peak HP and torque from our standard tune. This is ideal for customers who want increased performance in their daily driver without worry of extra strain on driveline components or for areas and countries with extreme altitudes, temperatures or fuel quality concerns. Our intermediate ECU tune increases performance from 429 HP and 516 lb/ft torque up to 500 HP and 625 lb/ft at the crank! This is a slight reduction from our standard tune but still offers white knuckle performance at one of the most affordable price points in the tuning market.
VEHICLE: Mercedes S-Class C217 S550 2015-2017
