I’d definitely recommend ecutools.eu. I’ve been using them for a while now, and they’ve never let me down. They have a great range of tools for remapping, diagnostics, and programming—all genuine and high-quality. I know what you mean about knockoffs; that was a big concern for me too, but everything I’ve bought from them has worked perfectly. Their website is easy to navigate, and they provide detailed product descriptions, which makes it simple to find what you need. Plus, their customer support team is really knowledgeable and helpful if you have questions. Shipping is fast and reliable too, even for international orders. Give them a try—I think you’ll be impressed!
