RENNtech Power Module (RPM) ECU -tune increases horsepower and torque across the entire power band. By modifying ignition timing, throttle mapping, optimizing air-to-fuel-ratios, and modifying boost mapping for turbo-chargers of the twin turbocharged 4-liter V8 -engine found in the Audi RS6, RS7, and RSQ8 gains up to +80 HP and 106 LB-FT.

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.

                - Audi RS6 (C8) 2019+
                - Audi RS7 (4K) 2019+
                - Audi RSQ8 (4M) 2019+
