GIAC calibrations are now available for the 991.2 Turbo!


GIAC, the first in the world to offer 991.2 programming as early as January of 2017, has expanded its product line to cover engine performance software for the base model 991.2 Turbo. GIAC's latest stage 1 calibration delivers peak to peak power gains of 60 - 65 horsepower and 40 - 50 Ft-lbs of torque. The program also offers smooth part throttle driving and gear transitions, but a substantial increase in power at full load.

Software features include:
- Added boost
- Changes to fuel and timing
- Higher torque limits

Performance gains displayed in the dyno plot shown here were achieved with the GIAC software upgrade only on 93 octane. Additional power increases may be observed with additional performance hardware and/or higher octane fuel. Thank you, Champion Motorsport, for your support during product development and testing.

The MSRP for GIAC software for 991.2 Turbo applications is $2900. All supported 991.2 and 982 computers initially require a "bench unlock" flash which can be done by GIAC or select GIAC dealers. Once unlocked these controllers can be flashed over the OBD port by any GIAC dealer. For questions or sales information, please contact or find your nearest GIAC retail location at
