Power Module 3.0L I6 Turbo EQ Boost ECU Tune

The RENNtech Power Module (RPM) ECU tune is engineered to elevate the performance of Mercedes-Benz AMG 53 M256 3.0L I6 Turbo EQ Boost engines. This module actively modifies key engine parameters, including ignition timing, throttle response, air-to-fuel ratios, and turbocharger boost mapping, to achieve substantial power gains across the entire RPM range. Based on dyno-measured figures, the tune can deliver up to an additional 59 HP and 97 LB-FT of torque, bringing the total output to 494 HP and 480 LB-FT. The RPM module itself is constructed within a robust CNC-machined 6061 aluminum enclosure, ensuring durability and a premium finish. It features pre-labeled wires and connectors for straightforward installation. A unique bypass function is included, allowing the user to quickly revert the vehicle to its stock performance settings by installing the bypass in place of the module. For a complete return to the original state, the entire harness can be uninstalled. With over 30 years of ECU tuning expertise, RENNtech has dedicated countless hours to in-house research, development, and long-term testing to ensure the quality, performance, and reliability of this upgrade. The module is compatible with several AMG 53 models, including the E 53 AMG (W213/S213), CLS 53 AMG (C257), GT 53 AMG (X290), and GLE 53 AMG (V167). Professional installation is recommended. Buyer Beware: It is important to note that there have been reported failures of the stock turbochargers in the Mercedes-AMG 53 series M256 engine. Increasing the power output with this module without upgrading the OEM turbocharger may increase the risk of turbo failure. For those seeking further performance enhancements and to mitigate this risk, RENNtech offers STAGE 1 and STAGE 2 Turbo Upgrade solutions.
