Hello, I'm Dennis Bratland. I noticed that you added or changed content in an article, Engine tuning, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page.

Please seek unbiased sources with no conflict of interest, and avoid motioning names of vendors in articles unless there is significant support for doing so in independent sources. Encyclopedia articles exclude WP:HOWTO advice such as telling readers what "you" should or should not do. Dennis Bratland ( talk) 18:48, 21 December 2018 (UTC) reply
