Unlock the Full Potential of Your BMW's ZF 8-Speed Automatic

The ZF 8HP is one of the most advanced automatic transmissions ever fitted to a performance vehicle—but from the factory it's calibrated to satisfy emissions, comfort and broad market requirements, not to maximise performance.

At Built by Boost & Tune, we develop bespoke XHP TCU calibrations tailored specifically to your vehicle, engine combination and driving style. Whether you're running a stock daily driver, a full bolt-on street car or an 1,500+ horsepower race build, our custom transmission tuning unlocks the true capability of your drivetrain.
