GIAC has been at the forefront of Bentley performance since 2005, when we became the first company in the world to offer OBDII port flashing for the Continental GT. By replacing physical hardware soldering with seamless digital calibration, we set a new standard for value and convenience that continues today.

Our current software lineup covers a wide range of Bentley?s most iconic powerplants, offering massive power gains without sacrificing the refined drivability the marque is known for. GIAC calibrations offer more than just raw power. Every program is developed with rigorous monitoring of knock correction, air-fuel ratios, and wastegate duty cycles to ensure the optimum balance between performance and reliability.
