OMG. I have never attended a dyno run but even I can tell that there were at least two things that went wrong:

1. The torque figures are obviously wrong since the RPM was miscalculated as you can see from the slip.
2. The power figures are meaningless because shortly before max RPM was reached, power was reduced because of overheating.

You can see this at 1:39 in the video. The coolant sign came on and max RPM was reduced to ~7000 by the safety cutoff. During this run, maximum power was never reached.

Did the guy miss to install the neccessary air duct for cooling? I can only see the open hood.

Get your money back. That dyno run did nothing but put stress on your engine.
