Calibration Details
In-House Powertrain Calibration
McLaren's 750S represents the pinnacle of the Super Series lineup, with 740 HP and 590 ft-lbs from the refined M840T 4.0-liter twin-turbo V8. Despite being closer to the engine's factory-rated limits than the 720S, the 2024 750S still carries conservative ECU calibration margins in boost pressure and ignition timing, margins that our engineering team has carefully mapped and validated through dyno testing and real-world driving.
Stage 1 unlocks +125 HP and +115 TQ for a total of approximately 865 HP and 705 ft-lbs. Our calibration optimizes the revised turbocharger response curve, advances ignition timing at the mid-range RPM points where the factory is most conservative, and refines the fueling strategy for consistent peak power on premium fuel. The result is a 750S that accelerates harder from any speed, with quicker turbo response and a more immediate throttle feel. Stage 2 takes output to 905 HP and 750 TQ, breaking the 900 HP barrier with reliable, daily-drivable calibration. Developed entirely in-house by Mega 3 Performance, with 500+ McLaren projects of proven track record. ECU map switching and antilag systems available.
