The RENNtech Power Module (RPM) ECU tune delivers significant horsepower and torque gains across the entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, and modifying boost mapping for turbo-chargers the Mercedes-Benz M176 4.0 V8 BiTurbo EQ Boost -engine gains up to +80 HP and + 101 LB-FT, based on Dyno measured power figures.

The RENNtech Power Module is contained in a CNC machined 6061 aluminum enclosure with pre-labeled wires and connectors. The RPM module comes with a bypass that can be installed in place of the module to quickly turn the vehicle back to stock performance. The harness can be uninstalled to return the vehicle to stock completely. Through our 30+ years of ECU tuning experience, countless hours of in-house research, development and long-term testing ensure that our ECU upgrade offers the best in quality, performance and reliability.
