All our M3P transmission and driveline parts are designed, engineered, and manufactured in the USA. We have invested heavily in our driveline offering to ensure maximum reliability and performance for high-horsepower McLaren applications.
All of our calibrations are written and developed in-house and not outsourced. Our calibrator is owner/engineer Safa, who has been tuning for 15 years and is currently the only person in the world to unlock full control of the McLaren TCU. Safa's expertise extends to developing calibrations for the TCU and CPC controller for Mercedes platforms, plus ECU and TCU tuning for many of today's popular high performance European cars.
We maintain inventory of our engine and M3P driveline parts, which enables us to complete McLaren builds within 12-16 weeks. This timeline could be subject to change based on volume increases, which would be clearly disclosed at the time of build slot reservation.
The McLaren TCU tuning solution is exclusively available for our client builds only. The TCU calibration is a critical component that works in conjunction with our ECU tuning to achieve the full power potential and driveability in our comprehensive powertrain programs.
