First, the "857" on the display doesn't really correlate to anything particular. It's just a string read out of the config file.
Second, 790 at the wheels for a comparatively small set of mods isn't terrible at all. Certainly enough to squash unmodded Mustangs, Camaros, some Porches...
Third, there's a whole swamp of debate on dyno types and results. Just remember that a dyno is just a tuning device...what matters is how it works for you!
Get out there and enjoy it!
