GIAC has released their new software for the Porsche Carrera 991.2. GIAC’s software unlocks the potential of one of Porsche’s new turbocharged platforms.

GIAC is proud to release GIAC engine performance software for the 991.2 Carrera! This calibration delivers peak-to-peak engine estimate gains of 62hp and 111 ft/lb torque. Estimated crank power output is 446 horsepower and 474ft/lbs of torque on 91 octane pump gas. The program offers smooth part throttle driving and gear transitions, but a substantial increase in power at full load.
