BMW M550xi 2019 Custom ECU Tuning

Elevate the performance of your 2019 BMW M550xi with our high-performance custom ECU tuning service. Our tailored tuning files are designed to meet the specific needs and specifications of your vehicle, ensuring optimal performance with ease of installation. With our remote installation service, you can enjoy a seamless upgrade without the hassle of a physical visit to a tuning shop.

Expert Tuning and Customization

At Stage 4 Tuning, we specialize in Stage 1, 2, and 3 custom ECU tunes, each requiring varying levels of modification. Our Stage 1 tune offers a straightforward upgrade without additional modifications, while Stage 2 requires downpipes and exhaust for enhanced performance. For vehicles with upgraded turbos, E85 fuel, or bespoke builds, we offer a custom quote to meet your specific requirements. Our service includes real-time data logging and map switching, allowing for precise adjustments and seamless transitions between custom maps for various driving conditions.

Unmatched Performance and Satisfaction

Our custom ECU tunes are designed to guarantee peak performance for your BMW M550xi, whether you're on the road or the track. With features like extending or adding burble, adjusting tunes for your octane rating, and calibrating for additional upgrades, our service offers a comprehensive solution for your vehicle's performance needs. We also provide top speed limiter removal, check engine light removal for downpipes (Stage 2, for off-road use only), and cold start delete options. With our 30-Day Performance Guarantee and the ability to switch back to your original ECU settings at any time, you can trust that your investment is in good hands. Contact us today to unlock the full potential of your BMW M550xi.
