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 +100 HP +84 LB-FT in the 4.0-liter BiTurbo V8 -engine (M177) found in the Mercedes-AMG GT-series of vehicle, 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.
