Then there must be something wrong with the in house dyno tester in VW R&D. I wonder if we from the water spinach country is better than those Germans when comes to this kinda test 
Not sure why is that we aren't seeing the flat torque as the manufacturer claimed.
Some dyno testers are calibrated periodically, if they do that, there is a accuracy report which is most of the time traceable and you can find out how accurate is the reading typically from 10% to 100% of the range.
I noticed most of the dynos here in this country, are not calibrated periodically unlike in the west. As calibration is at a premium, with revenue into consideration, here, most of the auto shops are not doing it.
BMW e90 320d has 380NM of torque rated on engine... Not sure why is that we aren't seeing the flat torque as the manufacturer claimed.

but when most of it are put on to the dyno... some even got 420NM on wheel..
the average figures is 375NM on wheel there about...
and mind u that is running shitty euro2 diesels and their cars is stock...
and no u can never get an exactly flat dyno results...
pseudo-flat got la... but u will never get a pure flat line...
