Description:
Our intermediate level RennTech ECU upgrade for the Mercedes 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.Â
Our intermediate ECU tune increases performance from 429 HP and 516 lb/ft torque up to 480 HP and 605 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.
ECU Tuning, also called Chip Tuning is a method of updating the electronic control units chip with higher performing software. Updating the ECU chips programming can raise horsepower, timing, fuel injection, electronic throttle control and valve timing.
Attention:
We have found the stock performance numbers vary from the baseline figures claimed by Mercedes Benz. We typically see higher baseline numbers than claimed by the factory.Power gains are calculated based on stock numbers measured by RennTech. Crank Performance Numbers are calculated with a 18% Drivetrain loss on 4MATIC SUVs.Our numbers will be dependent on conditions and fuel quality. 91+ Octane gasoline is mandatory with this Performance Upgrade.
