Overview

The RennTech Power Module (RPM) is a plug-in tune for the 2020-2023 GLA 45 AMG. It sits between the factory sensors and the engine computer and adjusts boost, timing, throttle and fueling on the 2.0L M139, so it adds power without reflashing the ECU. RennTech rates the GLA 45 AMG at up to 490 hp and 398 lb-ft with this upgrade, a gain of 68 hp and 30 lb-ft.
