Engine Tune

"Unlike other chips that hurt your car and put a strain on your engine, our chip will have your car running like new again with a smooth and OEM-like performance increase." That is how Engine Tune introduces itself. To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.7 out of 10.

On the page itself the strengths are clear: a clear heading structure and a clearly stated business identity. It is passable on partial sitemap and link coverage. What holds it back is the technical files AI engines look for, such as llms.txt or an open robots.txt, structured data describing the business and credibility markers like credentials or reviews.

Away from its own site, other sites link to it. Beyond that, the domain does not yet read as established, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on, nobody is discussing it where AI engines look and it does not come up on Reddit. Those are earned elsewhere on the web, not fixed on the site itself.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). The site links to no social profiles, so there is nothing tying the brand to a wider presence.
