aprWe’re excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Porsche 991.2 911 Turbo S 3.8T! Expect massive gains with 623-672 HP and 621-648 FT-LBS of torque on tap, depending on octane, from this simple software upgrade. Best of all, the upgrade flashes to the factory ECU via the vehicle’s OBD II port so there’s no ECU removal or physical modification necessary!


Our new suite of Porsche software comes after months of extensive research and development typically absent from the aftermarket. Our upgrade makes the engine more powerful and each driving mode more exciting. We’ve extensively calibrated the system to work flawlessly on the track with many additional safety routines in place to protect your engine in the most demanding scenarios. This was all made possible by our engineering teams pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment to feed valuable data to the team for analysis. After various track days, acceleration tests, and dyno sessions, we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of new safety features built in.
