This is a comprehensive Stage 2 tuning package for the Audi S3 (8V), equipped with the powerful 2.0 TFSI engine and a Siemens/Continental Simos 18.1 ECU. This package is designed for vehicles that have been mechanically upgraded with a high-flow downpipe to achieve maximum performance.
The package provides two distinct Stage 2 calibrations, both with the top speed limiter (Vmax) removed. The first file is a powerful tune for cars running a high-flow sports catalyst. The second file is an aggressive decat version that disables catalyst monitoring, perfect for a fully unrestricted exhaust system for dedicated off-road or track use.

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. The seller accepts no responsibility for misuse or non-compliant road use.
