S3 2.0 TFSI — MED9.1 387951 Bosch — Stage 1-3 Tuning Pack ECU Tune
This is the ultimate tuning package for the Audi S3 2.0 TFSI, equipped with the Bosch MED9.1 ECU. This comprehensive collection provides a full tuning path from a powerful daily driver to an extreme track machine, with files for Stage 1, Stage 2, and a specific Stage 3 setup.

The Stage 1 tune offers a fantastic performance increase for a completely stock car. Stage 2 is designed for vehicles with upgraded hardware (downpipe, intake, intercooler) to maximize the potential of the stock turbo. The Stage 3 file is an aggressive, all-out performance calibration specifically for vehicles that have been upgraded with a LO380 hybrid turbocharger and all other supporting modifications. This package gives you the ultimate flexibility for your S3 tuning journey.
