GIAC engine performance software for the 2016 - 2020 Porsche ® Panamera ® and Panamera 4 ® is now available. The GIAC stage 1 plus program includes increased boost, changes in fueling and timing, as well as higher torque limits to yield peak power of around 368 HP and 408 Ft-Lbs of torque on 91 Octane and 400 HP and 421 Ft-Lbs of Torque on 93 Octane (vs. the OEM program of 325 HP and 332 Ft-Lbs). The calibration keeps part throttle driving smooth and predictable while increasing full throttle power dramatically throughout the rev range. No other after market parts are required, however performance may be improved with additional upgrades.
