Mercedes-AMG S63 E Performance (W223) | RENNtech | RPM ECU Upgrade | 890 HP and 1062 LB-FT TQ

The RENNtech Power Module (RPM) ECU tune delivers significant horsepower and torque gains across the entire power band. By modifying boost mapping and keeping optimized air-to-fuel ratios, the entire power and torque curve is shifted upward delivering +49 HP +55 LB- FT in the 4.0-liter BiTurbo V8 -engine (M177) found in the Mercedes-AMG S63 E Performance  vehicles based on Dyno measured power figures.

The RPM is contained in a CNC machined 6061 aluminum case with pre-labeled wires and connectors. The RPM comes with a bypass that can be installed in place of the module for quickly turning the vehicle back to stock. The harness can be uninstalled for returning the vehicle back to stock.

Through our 30+ years of ECU tuning experience, countless hours of in-house R&D, and long-term testing the RPM ECU upgrade offers the best in quality, performance, and reliability.
