Those logs from on the dyno or on the road, I think you're saying they were logged whilst it was on the dyno? You'd hear the changes in engine noise as IQ took a dump if that graph was genuinely correct - get whoever is operating the dyno to show you the logs of wtf is going on with the dyno, if a braked dyno, it should be able to show you the brake output and load cell measurements. Considering some of the antics I've seen from various dyno operators who are literally clueless, nothing would surprise me these days.
I'd currently go with bullshit dyno and/or inept dyno operator until otherwise proven wrong.
EDIT: The way the dieselgate "defeat device" cheat works would instantly detect a non-emissions testing scenario, it's based upon distance/time curves which coincide with various test cycles using upper and lower bounds which are pretty strict (later versions also added detection for steering wheel movement, lol), I'd wager it's highly, highly unlikely you'd hit those in a power run scenario...
No it was logged on the road, unfortunately not logged on the dyno as well.
