GIAC Stage 1+ is now available for 2018 - 2021 Audi A6/A7 C8 ecu upgrade 55TFSI models.
The GIAC stage 1 plus Audi A6/A7 C8 calibration for this 3.0-liter turbo includes substantial improvements in power and acceleration without sacrificing any part throttle smoothness or predictability. Drivers may even notice some improvements in shift quality due to the higher torque commands from the GIAC engine computer. Platform testing revealed that the power potential on 93 octane was quite a bit higher than what was possible on 91 octane, so the calibration was structured to fully take advantage of either fuel on the fly. Upgraded intake system, exhaust system, and inter-cooler are supported and may improve the results of the upgrade even further.
GIAC engine performance tuning for the Audi ® A6 / A7 55 TFSI C8 (3.0 Liter Turbo) is now released for OBDII flashing!
