WELCOME!
Welcome to our new site! If you're new to this site and our partner site, RaceCarBook.com, we're glad you're here. Our sites aim to provide information and tuning tips for racers and engine tuners in the motorsports world. Specifically, we provide information and tools for mechanical fuel injected racing.
If you're here from Air Density Online, this might look a little familiar to you. We hope so! We have kept the new site as similar to the old site as possible in order to make the transition as easy as we can. That being said, we plan on adding new features and making this more useful than the old site.
We will be officially moving all ProCalc & ProTune users over here at the end of this month. We will be in communication with those customers as we go. In the meantime, look around and don't hesitate to send us any questions or comments.
