GIAC Stage 1 software calibrations, compatible with factory exhaust and intakes, are now available for the Audi S4 and S5 3.0T FSI. This software calibration offers dramatic improvements over the factory software. Special thanks to all of our beta test cars for providing GIAC with great data and feedback prior to the software release. With our 6 car beta test program, we were able to ensure the 3.0T FSI software was rock solid in various temperatures, octanes and elevations, whether on the street, strip, or track.  Audi has truly brought back the heart of the S cars with this 3.0T power plant.  We are excited to be tuning such a strong engine and we will keep you updated as our product line for S4 applications grows.
