Calibration Details
In-House Powertrain Calibration
The 2017 McLaren 650S, the model's final production year, delivers 641 HP and 500 ft-lbs from its M838T 3.8-liter twin-turbo V8. After years of refining our calibrations on this proven platform, our engineering team at Mega 3 Performance has a deep understanding of exactly where the factory ECU leaves performance on the table and how to safely extract it.
Stage 1 delivers +80 HP and +80 TQ, bringing the 2017 650S to approximately 721 HP and 580 ft-lbs. We achieve this through carefully optimized boost pressure maps, ignition timing adjustments, and fueling refinements that target the mid-range and top-end where the factory tune is most conservative. The driving experience transforms: quicker turbo response, a stronger pull through the rev range, and significantly improved passing power. Stage 2 raises the total to 746 HP and 600 TQ for owners seeking maximum output. With over 500 McLaren projects completed worldwide, our calibrations are trusted by 650S owners across the US, Europe, and the Middle East. All tunes are optimized for 93 octane and available with ECU map switching and antilag.
Performance Stages
Tuning through Stage 1 & Stage 2 ECU calibration works to improve horsepower, torque, and overall engine responsiveness. By optimizing the engine management system, we unlock the true potential of your vehicle, delivering a smoother powerband, enhanced throttle response, and a dramatically more engaging driving experience, all while maintaining factory reliability and safety parameters.
