Performance Gains

Engineered to deliver explosive midrange torque and a smooth, linear powerband, the Stage 1 calibration transforms everyday drivability into true performance-car dynamics — all while retaining full factory safety strategies for EGT, knock, and lambda control.

Included in the Package

• ECU Unlock Service

• Custom-calibrated Stage 1 Tuning 

• XHP Gearbox Software Upgrade — optimized transmission calibration for faster shifts, improved torque handling, and enhanced launch control, as well as increased clutch pressure. 

• In-house Dyno Tuning Session — calibration and validation on our state-of-the-art Hub dynamometer for precise, repeatable results.

Vehicle Drop-off & Turnaround

For this service, your vehicle must be booked in and left with us for up to 3 working days.
This period allows time for:

• ECU removal and unlocking

• Custom calibration and dyno tuning

• Quality assurance and testing

Our team will keep you updated throughout the process, and your vehicle will be ready for collection once tuning and validation are complete.

Instant throttle response, relentless midrange power, and an engaging drive that redefines the S58 experience — all while maintaining OEM reliability and refinement.
