Calibration Details
In-House Powertrain Calibration
With 789 HP and 590 ft-lbs from the M840TR 4.0-liter twin-turbo V8, the 2020 McLaren Senna is already one of the most extreme road-legal track cars ever built. Its carbon fiber construction, active aero, and extreme weight reduction create a platform where every additional horsepower has a measurable impact on lap times. Our in-house ECU calibration is designed to maximize the Senna's track potential while maintaining the reliability that matters during extended sessions.
Our Stage 1 calibration adds +125 HP and +115 TQ, bringing the 2020 Senna to approximately 914 HP and 705 ft-lbs. The M840TR's race-specification turbochargers handle the increased boost pressure with ease, and our optimized ignition timing and fueling maps ensure consistent power delivery throughout extended track use on 93 octane. The Senna's 1,198 kg dry weight means the power-to-weight ratio with our Stage 1 tune is exceptional, placing it in the performance territory of purpose-built GT3 race cars. Stage 2 pushes to 954 HP and 750 TQ. Antilag provides race-style turbo response out of slow corners, and ECU map switching allows stock calibration for road driving. Developed by Mega 3 Performance.
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.
