McLaren GT Stage 1 Multi-Map Tune & McLaren 765LT Stage 3 | 1082 HP

In this episode, we continue work on two McLaren projects at DEIZ GARAGE. The first car is a McLaren GT, which receives our in-house Multi-Map ECU tuning. After baseline dyno testing, we begin live tuning with real-time data logging and calibration adjustments. The car is equipped with multiple power modes, including a stock map, a Stage 1 performance map, a dedicated pops and bangs map, as well as additional safety and drivability features. All maps can be switched instantly using the factory controls, even while driving. The second part of the video focuses on our McLaren 765LT Stage 3 project. The car features a full TopCar carbon fiber body kit, upgraded fuel system, TTE turbochargers, billet intake components, a performance exhaust system, and a Wavetrac limited-slip differential. The goal was to create a powerful yet reliable package while retaining the factory engine internals. Following final dyno calibration, the 765LT receives five different power maps, including daily driving modes, high-performance pump fuel maps, a race map for E30–E40 fuel blends, and a limited-power safety mode. The project achieved a final dyno result of 1,082 HP, while maintaining multiple safety strategies designed to protect the engine, turbochargers, and exhaust system. This project demonstrates how unique styling, advanced engineering, and over one thousand horsepower can be combined into a reliable and usable road car. ⸻ If you want performance tuning in Dubai: Learn more / book a project: https://deiz-garage.ae Contact us via WhatsApp: https://api.whatsapp.com/send?phone=9...
