Calibration Details
In-House Powertrain Calibration
The 2023 McLaren 765LT continues as the benchmark Longtail, 755 HP, 590 ft-lbs, and a weight reduction of 80 kg over the 720S thanks to carbon fiber body panels, titanium exhaust, and lightweight interior trim. The M840T 4.0-liter twin-turbo V8 is a proven platform that our engineering team understands at an intimate level, and the 765LT's upgraded hardware means it tolerates additional power exceptionally well.
Stage 1 adds +125 HP and +115 TQ for a total of approximately 880 HP and 705 ft-lbs. Our calibration pushes the turbochargers harder through the mid-range, advances ignition timing for premium fuel, and refines the fueling maps for consistent power at high load. The impact is immediate: more explosive acceleration, a stronger top-end charge, and quicker response to throttle inputs. Stage 2 reaches 920 HP and 750 TQ, making the 765LT one of the fastest things on any track surface. Our antilag system provides race-style turbo response, and ECU map switching enables instant reversion to stock. Developed and validated entirely in-house at Mega 3 Performance, backed by 15+ years of performance engineering expertise.
