Results? Unless they've got a time machine those are predicted figures.... 
Done my own dyno run twice at college and this is how were told - pull away in 4th and floor the throttle, the dyno starts reading at 30mph (and feels like youve hit a puddle at that point) then keep on the throttle until you start losing bhp (or hit the limiter). Then let off the throttle to run down to calculate the tranny losses. Shouldn't damage the car at all, however, due to the extra 'strain' from the dyno over the normal road surface, you 'can' get overboost problems show up with 'quick' cars. Basically in normal driving youre on full throttle for only few seconds usually as thats all it takes to get to illegal speeds, on the dyno it takes 10+ seconds so the turbo gets more abuse than normal. I got an overboost fault doing my second run and put the car into limp mode, but apparently its not uncommon.
