GIAC Software Now Available for 3.4 L 981 Cayman GTS Applications!


GIAC software is now available for the 3.4 L Porsche 981 Cayman GTS. This software calibration accommodates 91-93 octane (95-98 RON) fuel with the factory exhaust and intake system.

Notable features include the following:
  • Improved throttle response
  • Raised redline for perfect timing of shifts (optional)
  • OEM drivability
  • Substantial power gain throughout the rev range after 4000 rpm
