BMW M50d Stage 1 Remap

The BMW M50D is one of the most impressive tri-turbo diesel engines ever produced, and with a DC Remapping Stage 1 calibration, we push it well beyond its factory limits. Our team has spent thousands of hours researching and developing calibrations specific to this engine, ensuring every map we write is both accurate and reliable.

It's worth noting that BMW's claimed figure of 381bhp is rarely, if ever, achieved in the real world. Our stock baseline dyno runs consistently show the M50D producing closer to 342bhp, nearly 40bhp short of BMW's brochure figure. This is common across the platform and is not a fault with your vehicle; it simply means there is even more headroom for our calibration to work with.

Our power and torque improvements are designed to stay within the safe limits of your engine, ensuring your vehicle remains reliable and safe to drive. We carry out a thorough vehicle health check before any tuning takes place, identifying any potential issues before we begin.

With our Stage 1 tune, you can expect increases of between 40–50 horsepower and 60–80 Nm of torque, all without requiring any hardware modifications to your vehicle.
