GIAC software calibration for the C6 A6 3.0t is now available!


Switchable software calibrations, compatible with OEM exhaust and intake systems, for the Audi A6 3.0t (C6 platform) are now available through GIAC's worldwide dealer network. With the software being uploaded through the vehicle's OBDII port, there is no need for ECU removal.

GIAC software calibrations offer dramatic performance increases when compared to the factory engine software, all while retaining factory levels of drivability. Software details include:

  • Improved throttle response
  • Optimized boost and air fuel ratios
  • Removal of speed limiters
  • Power gains from 70-100 hp & 25-35 ft. /lbs. of tq at the wheels (hardware dependent)
  • On-the-fly program switching for multiple performance modes.

Testing on GIAC's in-house Mustang MD-500 dynamometer measured power gains of 69 horsepower and 25 ft. /lbs. of torque over OEM software. With an upgraded intake, testing measured power gains of 87 horsepower and 34 ft. /lbs. of torque over OEM software. All power numbers were measured at the wheels, on 91 octane fuel. To compare these numbers to manufacturer rated numbers, an approximated 25% drivetrain loss should be factored in.
