S58 F/G Series Immotus Custom Tune

The Immotus Performance custom tuning calibration for the BMW S58 platform is engineered to extract maximum performance from BMW’s 3.0L twin-turbocharged inline-six found in the latest M models. Our calibration precisely refines boost pressure, ignition timing, fuel delivery, torque modeling, and load control to deliver substantial horsepower and torque gains while maintaining factory-level drivability and refinement.

Each tune is custom-built around your specific configuration—whether stock turbos, upgraded downpipes, flex fuel systems, hybrid turbo setups, or full bolt-on builds. We carefully manage intake air temperatures, boost ramp rates, and fueling strategies to ensure consistent, repeatable performance under demanding conditions while prioritizing engine safety.

The result is explosive mid-range torque, relentless top-end pull, sharper throttle response, and the aggressive performance character expected from the S58 platform.
