Spotted a wrong number, want a tool that isn't here yet, or need a leaderboard entry removed? I read everything. Corrections are especially welcome — accuracy is the whole point of the site.
The fastest way to reach Tuning4U is email:
It's a one-person project, so replies aren't instant — but genuine bug reports and corrections get looked at quickly.
Reporting a wrong result
If a calculator looks off, it helps a lot to include:
- Which tool (a link to the page is perfect).
- The inputs you used — the share link on each tool encodes them, so you can just paste that.
- What you expected and where the number came from (a manual, a known figure, another source).
Removing a leaderboard entry
Want a game leaderboard entry taken down? Email the display name and roughly when you submitted it, and it'll be removed. See the privacy page for exactly what a leaderboard entry stores.

Missing a calculator, a fuel, a unit or a feature in My Build? Send it over. A lot of what's on the site started as a single request.
