Package Overview
M1R Program
The M1R Program is a bespoke performance package developed exclusively for the McLaren P14 platform. Engineered to elevate the factory powertrain into a fully integrated high-performance system, the M1R produces approximately 950HP and 700TQ on premium unleaded fuel. When paired with the race calibration and race fuel, output increases to an exceptional 1,400HP and 890TQ.
Build Process
Every M1R build begins with a comprehensive vehicle detail and multi-point inspection before the engine and transmission are carefully removed by M3P's highly trained technicians. The powertrain is then fully disassembled and meticulously inspected by our machine shop, where the engine receives premium internal upgrades including CP-Carrillo billet steel connecting rods, forged aluminum CP-Carrillo pistons, CNC-machined cylinder heads, and a series of proprietary enhancements engineered to support extreme power levels while maintaining long-term reliability.
Once assembly is complete, the engine is reinstalled and paired with M3P's in-house engineered turbo system. The package features BorgWarner EFR turbochargers, upgraded wastegates, proprietary dual-pass air-to-water intercoolers with advanced internal surface features integrated into their 3D-printed AL6061 end tanks, and a fully 3D-printed Inconel exhaust system. Every component has been developed using advanced CAD modeling and high-resolution 3D scan data to maximize packaging efficiency, airflow, thermal management, and overall performance.
Extensive Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), and real-world validation testing have resulted in what we believe is one of the most advanced, efficient, and capable entry-level P14 upgrade packages available today.
To support the increased performance, the driveline and fuel system receive targeted upgrades along with ECU and TCU calibrations tailored to the selected fuel configuration.
Every M1R vehicle built by M3P is backed by a 24-month / 24,000-mile limited powertrain warranty (whichever occurs first; restrictions apply).

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 3-4 months. 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.
Absolutely! We provide a comprehensive 2-year/24,000-mile powertrain limited warranty with all our builds. Our confidence in the quality and reliability of our work allows us to offer warranty coverage that exceeds what any other McLaren tuning specialist provides.
Our performance packages deliver significant power increases: M1R up to 1400HP, M2R up to 1550HP, and M3R up to 1700HP. Each package includes full engine and transaxle builds, custom 3D printed parts, Syvecs ECU with map switching, and comprehensive TCU/CCU tuning.
Yes, we specialize in high-performance tuning for McLaren, Mercedes-AMG, Ferrari, Lamborghini, Porsche, and other exotic vehicles. Our expertise covers ECU tuning, TCU optimization, and comprehensive powertrain upgrades for various supercar platforms.
