Overview

The RennTech Power Module (RPM) is a plug-in tune for the 2023-2026 C 43 AMG. It sits between the factory sensors and the engine computer and adjusts boost, timing, throttle and fueling on the 2.0L M139 turbo I4, so it adds power without reflashing the ECU. RennTech rates the car at 464 hp and 405 lb-ft with this upgrade. That is a gain of 48 hp and 36 lb-ft.

Key details

The module raises horsepower and torque across the rev range rather than only at peak. It lives in a CNC-machined 6061 aluminum housing with labeled wiring and connectors, and a supplied bypass plug puts the car back to stock output in minutes.

Features

  • CNC-machined 6061 aluminum enclosure
  • Includes a bypass plug to return to stock performance quickly
  • Remove the harness and the car is completely back to factory
  • No ECU flash required

What is included

  • RennTech Power Module
  • Vehicle-specific wiring harness
  • Bypass plug
