The factory tune on your DDE4 ECU was written to keep fleet managers happy and warranties alive — not to make you fast.

OZWORX rewrites that story.

Our custom remaps for the DDE4 platform (BMW M57 engines) unleash the real potential buried in your diesel’s veins — sharper throttle, harder pulls, raised torque limits, and boost that actually means something. Whether you’re dailying, towing, or breaking necks sideways, this map brings the chaos back to compression ignition.

Built for the bold. Tested on the streets.
