Softronic ECU Tuning Package for Porsche 991.2 Carrera (2017–2019)

Description

The Softronic 991.2 Carrera Performance Software is an advanced ECU tuning solution designed to significantly elevate the performance of the Porsche 911 Carrera, Carrera S, and Carrera GTS from model year 2017 onward (991.2 chassis). Instead of replacing hardware, this software flash optimizes the engine’s digital control unit to enhance boost control, fueling, and ignition timing — resulting in dramatically increased horsepower and torque, stronger throttle response, and a more engaging driving experience. The calibration is developed specifically for the 3.0 L DFI engine and includes customizable options that let you tailor aspects of engine behavior to suit your driving goals.
Typical gains and results are achieved using 93-octane fuel on stock vehicles, making this a compelling upgrade whether your 911 is stock or has supporting bolt-on modifications.
