The Porsche Cayenne Turbo GT represents one of the most powerful high-performance SUVs in the Porsche lineup. For this project, DEIZ GARAGE completed a comprehensive Stage 2 performance upgrade developed in collaboration with MORENDI.
The vehicle in stock configuration is equipped with a 4.0-liter V8 biturbo engine (EA825 platform) producing between 640 and 659 horsepower depending on market specification, with 850 Nm of torque and a factory 0–100 km/h time of 3.3 seconds.
The Stage 2 upgrade begins with SFD2 unlock, allowing direct access to the Bosch MG1CS008 ECU. Once unlocked, the system receives a complete recalibration including fuel maps, boost pressure control, ignition timing, and overall engine management optimization.
Additional work includes optimization of thermal management and transmission shift strategy to ensure stable performance under load. Depending on configuration, the upgrade may also include OPF/GPF or catalytic converter delete upon request, along with the installation of high-performance downpipes, either high-flow or catless.
The calibration is developed for 98/100 octane fuel and validated for operating conditions in UAE, European, and CIS climates.
Following the upgrade, the Cayenne Turbo GT reaches approximately 750 to 800+ horsepower and up to 1050 Nm of torque. Acceleration improves to around 0–100 km/h in approximately 2.9 seconds, with noticeably stronger top-end pull and smoother power delivery across the entire rev range.
Despite the performance increase, the setup maintains everyday usability while preserving safety margins and mechanical reliability.
This project demonstrates DEIZ GARAGE’s collaboration with MORENDI to deliver advanced ECU calibration and performance upgrades tailored for high-performance Porsche platforms.
