GIAC has released performance programming for the 2018 - 2021 Audi ® B9 RS5. The GIAC Stage 1 Plus calibration maximizes engine performance for a range of premium octane levels from 91 to 94 (r+m)/2 or 95 to 100 RON. This program dramatically improves the performance of the RS5 with out the use of any additional hardware upgrades.
The GIAC Stage 1 Plus increases peak horsepower by 32 HP and 66 ft-lbs on 91 octane, while adding 71 HP and 78 ft-lbs on 93 octane. These gains bring the peak power potential to 514 HP and 545 Ft-Lbs of torque. The power delivery is consistent throughout the rpm range, with a largest torque gain of 84 Ft-Lbs at 4000rpm on 93 octane and 77 Ft-Lbs at 4300rpm on 91 octane. While full throttle acceleration is notably enhanced, part throttle driving remains as smooth as the OEM calibration.
