Yea, looks like they are baselining with it apart, probably for testing adn back to back runs with mods.
I saw it hit 557hp which I believe is dead-on for stock with 13% drivetrain loss which is what SRT has quoted for previous gens as a good reference, in fact the gen5 could have a little more drivetrain loss due to the 3.55, etc., so that may even be a farily strong car. But it is a dyno, which is more a tuning tool than an accurate overall measure of output due to variability etc.
I wonder what they'll do to try to get power, seems limited at the moment without a MOPAR PCM like the gen4s got for add-ons, the coding issue is a tough one.
They certainly now how to have fun with it though and break it in right!! Woohoo, loved that.
