Calibration Details
In-House Powertrain Calibration
The 2024 McLaren 765LT carries the same proven M840T 4.0-liter twin-turbocharged V8 producing 755 HP and 590 ft-lbs, paired with the Longtail's extreme weight-saving measures and track-oriented aerodynamics. As one of the most exclusive current McLarens, the 765LT demands a calibration approach that matches its engineering, which is exactly what our in-house team delivers.
Our Stage 1 calibration for the 2024 765LT adds +125 HP and +115 TQ, bringing total output to approximately 880 HP and 705 ft-lbs. We optimize the turbocharger response curve for quicker spool, advance ignition timing at the RPM points where the factory is most conservative, and refine fuel injection for 93 octane. The 765LT's lightweight construction amplifies every horsepower gained, acceleration is more intense, braking zones shrink, and lap times drop. Stage 2 unlocks 920 HP and 750 TQ for owners who want to maximize their 765LT. ECU map switching and antilag are standard add-on options. All calibrations developed and tested in-house by Mega 3 Performance, available worldwide through our remote flash service.
