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.

All tuning files were acquired through official EVC.de resellers and verified on a professional dynamometer. Each calibration corresponds to the developer listed in the “Modified By” section — performance graphs may be available on their official website. These files are intended for motorsport or off-road use only. Ensure proper installation and do not operate the vehicle aggressively without first confirming mechanical condition.
