Optimised for the supercharged 3.0 V6 TFSI engine, this Stage 2 remap delivers a sharper, more responsive driving experience in the Audi S4 B8 (2011). Built on Siemens/Continental SIMOS8.4 with software ID S8400G1000000, it increases airflow efficiency, recalibrates torque/load limiters, and fine-tunes ignition strategy for use with upgraded hardware (intake/exhaust). Supplied with original file for safety.
