GIAC performance programming adds substantial power to the 981.2 718 Boxster ® S and Cayman ® S, increasing the engine estimated crank power output to 405 - 415 horsepower and 415 - 425 ft/lbs of torque on 93 octane. Peak to peak gains were 45 HP and 44 Ft-Lbs, however average gains were 60 Ft-Lbs between 3600 to 5100 RPM and 50 HP between 4000 to 6300 RPM. In addition to the added power, the program also offers smooth part throttle driving and gear transitions.
Software features included:
- Increased boost
- Changes to fuel and timing
- Higher torque limits
Special thanks to Champion Motorsports for their help in the development process. Performance gains displayed in the plots shown were calculated from raw wheel power data of OEM and GIAC programming tests on Champion Motorsports Dynojet Dyno. A factor of 1.1 to account for parasitic losses was used to create the Engine estimated curves. No additional upgrades were used during testing, although larger power increases may be observed with additional performance hardware and/or higher octane fuel.
MSRP for this software is $1,800 USD. All 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 more information, contact your local GIAC dealer or send your questions to firstname.lastname@example.org.
