Your 2019 Mclaren SENNA deserves more. Our dyno-proven ECU tune delivers real-world gains you'll feel from the first drive.
Calibration Details
In-House Powertrain Calibration
The McLaren Senna demands a tuning approach that matches its uncompromising engineering philosophy. The 2019 model's M840TR 4.0-liter twin-turbo V8 produces 789 HP and 590 ft-lbs, the most powerful version of this engine family fitted to a road car. The "TR" designation indicates race-specification turbochargers and engine calibration, creating a platform that responds exceptionally well to further ECU optimization.
Stage 1 on the 2019 Senna unlocks +125 HP and +115 TQ for a total of approximately 914 HP and 705 ft-lbs. Our calibration pushes the upgraded turbochargers to their optimal operating point, advances ignition timing beyond the factory's conservative limits, and refines fueling for maximum power on premium fuel. Combined with the Senna's carbon fiber monocoque, active aerodynamics, and minimalist interior, these gains make the car brutally fast on track, corner exit speeds increase, straight-line acceleration becomes even more violent, and braking zones shrink. Stage 2 reaches 954 HP and 750 TQ. All calibrations developed and validated in-house by Mega 3 Performance with ECU map switching and antilag. Our 500+ McLaren calibration track record ensures precision.
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.
