Overview

For owners of the 2025-2026 AMG GT 63 S E Performance Coupe who want real gains but a fully reversible install, RennTech's Power Module is the answer. The CNC-machined module connects through a vehicle-specific harness and refines boost, ignition and fueling for the 4.0L M177 twin-turbo V8 E Performance. RennTech rates the car at 808 hp and 895 lb-ft with this upgrade. That is a gain of 54 hp and 44 lb-ft.

Key details

Boost targets are raised while air-fuel ratios stay in a safe window, lifting the whole power and torque curve of the AMG GT 63 S E Performance coupe. The unit sits in a machined 6061 aluminum case with pre-labeled leads, and a bypass plug returns the car to factory output quickly.

Features

CNC-machined 6061 aluminum enclosure
Includes a bypass plug to return to stock performance quickly
