Description
Unlock the full performance potential of your BMW S63-powered vehicle with the dAHLer Engine Performance Tuning Module, a precision-engineered power upgrade designed to deliver seamless integration, increased power, and enhanced driving dynamics. Developed in Switzerland and made in Germany, this module is engineered to work in harmony with the factory ECU, providing optimized boost, ignition, and fuel parameters for a more exhilarating driving experience—without compromising reliability or drivability.
With gains of up to +9 horsepower to the wheels on a stock setup, the dAHLer tuning module enhances throttle response, mid-range torque, and overall vehicle performance. Installation is simple and non-invasive thanks to OEM-style connectors that plug directly into your vehicle’s camshaft and boost pressure sensors—no DME removal or complex modifications required.
What sets this tuning module apart is its smartphone integration via the free dAHLer Mobile App for iOS and Android. This allows you to wirelessly toggle between three customizable performance maps, activate or deactivate the tune at will (even while driving), and configure a warm-up timer for safe engine operation. The module is fully reversible, EPA compliant, and TÜV approved, ensuring both emissions compliance and long-term serviceability.
Whether you're daily driving or pushing your M car on the Autobahn, the dAHLer Engine Performance Tuning Module delivers OEM-level smoothness and responsiveness—just more of it.
