GIAC is proud to release GIAC engine performance software for the 991.2 Turbo S. This calibration delivers peak to peak gains of 50 - 60 horsepower and 40 - 50 torque. The program 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
GIAC is the first tuner in the world to offer 991.2 Turbo S engine software calibrations.
Performance gains displayed in the dyno plot shown here were achieved with the GIAC software upgrade only. 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.
