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.
