We have a tune available for your F10 that lets you unlock the full potential of the S63B44T0!
Precision ECU Tuning for the S63B44T0
Few cars manage to be as calm, capable, and unhinged as the BMW F10 M5. Behind its tidy executive look sits one of BMW’s greatest engines — the S63B44T0, a 4.4-litre twin-turbo V8 that changed what “fast sedan” means. Even in stock form it’s brutally quick, blurring the line between business trip and back-road brawl. However, like many modern performance cars, the factory tune leaves plenty of power untapped. That’s where we step in.
Releasing the Power
At AutoUpgrades, we take what BMW started and finish it properly. By contrast, our tuning goes beyond minor adjustments — it refines the whole power delivery. By precisely tuning the factory ECU, we free up the power, torque, and throttle response the S63 was built to deliver but never could. As a result, the M5 feels sharper, hungrier for revs, and far more responsive. Boost builds smoothly, torque spreads wider, and the throttle reacts the moment you touch it — exactly how it should have felt from day one.
When BMW calls the M5 a Super Sedan, they’re being polite. In reality, our tune turns that polite claim into an argument with physics. The tuned S63 doesn’t just move — it lunges forward with intent. Thanks to the stronger mid-range torque, acceleration keeps climbing long after most cars have given up.
Engineered the Right Way
Power alone isn’t the goal. Instead, our process follows the same methods used in OEM development. We log, refine, and test each calibration before release. Therefore, the result is real performance with factory-grade reliability. You feel it in every gear — clean boost, smooth power, and control that stays consistent.
Transmission Tune for the ZF 8-Speed
If your M5 runs the ZF 8-speed automatic, we offer an optional transmission tune ($750) to match the engine perfectly. It sharpens shift logic, removes lag between gears, and tightens torque-converter lock-up for instant response. In addition, shifts happen faster and more precisely. Downshifts land cleanly, and full-throttle upshifts hit hard but smooth. Together, they make the car feel more connected to you than ever before.
What You’ll Notice
From the first drive, the difference is obvious. Throttle response is instant, boost comes on strong, and the familiar M5 growl turns into something more focused. Ultimately, this isn’t about making the car rough — it’s about giving you access to the M5 BMW’s engineers always intended to build.
If you want real performance based on engineering, not hype, the F10 M5 tune from AutoUpgrades is the standard. We measure, test, and refine until it feels OEM-plus — faster, sharper, and perfectly balanced.
