The DINANTRONICS X Performance Tuner (D440-0131) is a highly engineered, Bluetooth-enabled inline tuning module for a wide range of 2016-2021 BMW B58-powered models (240i/340i/440i/540i/640i/740i/X3 M40i/X4 M40i). The X enhances engine performance to levels the stock programming avoids, yielding maximum gains of up to +47 HP and +59 lb-ft of torque (Crank). This is achieved through a more refined tuning strategy that connects to additional inputs, ensuring optimal performance without affecting long-term reliability or on-board diagnostic systems.

The Bluetooth Smart functionality allows convenient access to 7 power levels and a bypass setting directly from your smartphone. The system is a perfect alternative for those who cannot alter their stock ECU, providing smooth and predictable power delivery while maintaining all factory safeguards. The unit is designed for a simple plug and play installation and is unaffected by dealer factory updates.
