🏁 BMW S58 PERFORMANCE PACKAGES

⚡ TRS STG1 — 650 BHP / 850 Nm

🔥 TRS STG2 — 700 BHP / 920 Nm

Unleash the true potential of your BMW S58 engine.

A complete in-house performance solution for 2020+ BMW M models equipped with Bosch MDG1 engine management — delivering supercar-level performance while maintaining OEM drivability, safety strategies, and reliability.

Whether you choose our TRS Stage 1 calibration on factory hardware or our full TRS Stage 2 package with supporting performance upgrades, every calibration is developed, tested, and validated in-house by TRS Performance.

From ECU unlocking and calibration development, through to hardware installation, gearbox optimisation, and hub dyno validation — every stage is completed under one roof.

🔓 IN-HOUSE ECU UNLOCKING NOW AVAILABLE

We offer a complete in-house unlocking solution for Bosch MDG1 ECUs using the latest Flex Glitch unlock method.

This advanced process requires ECU removal and opening, allowing our technicians to safely perform the unlocking procedure at our facility.

Once the ECU has been unlocked, it becomes fully OBD programmable, allowing future tuning, software changes, and calibration updates to be completed conveniently through the vehicle’s OBD port without repeating the unlock procedure.

Using our own TRS Performance custom tuning software, we are able to read, write, and develop bespoke calibrations directly in-house — giving us complete control over the tuning process from start to finish.

Alternatively, customers can also choose MG Flasher support after the unlock process, enabling OBD flashing, map switching, and software management through the MG Flasher platform.

Every TRS Performance calibration is developed, tested, and validated using our in-house hub dynamometer, providing a complete tuning solution from unlock through to final calibration.
