GIAC is proud to release GIAC engine performance software for the 991.2 Carrera! This calibration delivers peak-to-peak engine estimate gains of 62 hp and 111 ft/lb torque. Estimated crank power output is 438 - 446 horsepower and 455 - 474 ft/lbs of torque on 91 octane (upgraded exhaust for optimum power) . The program offers smooth part throttle driving and gear transitions, but a substantial increase in power at full load.
Software features included:
- Increased boost
- Changes to fuel and timing
- Higher torque limits
Special thanks to Rotiform for offering their in-house Carrera, which was used for testing on our in-house Mustang MD500SE dynamometer. The engine horsepower and torque graphs are estimated from wheel dyno tests using a correction value of 1.112. A wheel dyno comparison is also included. All testing of the OEM and GIAC programming, was done with an aftermarket exhaust on the car.
Performance gains displayed in the plots shown were achieved with the GIAC software upgrade with only using 91 octane. Additional power increases may be observed with additional performance hardware and/or higher octane fuel.
MSRP for this software is $2,200 USD and is flashed via ECU send-in only. For more information, contact your local GIAC dealer or us at email@example.com.
