Overview

The RennTech Power Module (RPM) is a plug-in tune for the 2019-2026 GT 43 AMG 4-Door Coupe. It sits between the factory sensors and the engine computer and adjusts boost, timing, throttle and fueling on the 3.0L M256 turbo I6 EQ Boost, so it adds power without reflashing the ECU. RennTech rates the car at 411 hp and 442 lb-ft with this upgrade. That is a gain of 49 hp and 73 lb-ft.

Key details

The module comes in a CNC-machined 6061 aluminum enclosure with labeled wiring. Fit the included bypass plug to go back to stock output fast, or remove the harness to return the car fully to factory.
