RENNtech M157 Biturbo ECU+ Upgrades are TÜV approved!
Our proprietary ECU+ upgrade for the Mercedes M157 Biturbo 4-MATIC engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.
- We have found the M157 engine 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 17% Drivetrain loss on 4MATIC vehicles.
- Our numbers will be dependent on conditions and fuel quality. 93+ Octane gasoline is mandatory with this Performance Upgrade.
- States known for poor fuel quality have to be supplied with a lower power setup. Please call for details and Race fuel options +1-561-845-7888.
