Description

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.

 

Notes:

  • 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 18% Drivetrain loss on SUVs.
  • 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.
