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 +84LB-FT in the 4.0 liter Biturbo V8 engine (M177) Mercedes AMG SL-series, 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.
From the factory, the SL 63 AMG is delivered with 577 HP and 590 LB-FT. With the RENNtech RPM, the performance numbers go up to 725 HP and 765 LB-FT, gaining up to +100 HP and +84 LB FT.
