What other data do you have?
Maybe the timing/boost are being pulled if you are over stretching it?

High loads/WOT at low RPM are where the timing becomes an issue....

The operator should have explained, or run it again IMO.

As said I should have noticed the dyno graphs looked off but after a busy day at work on the hottest day of the year was just keen to get home...

I'm 100% sure the dyno graph is more to do with the operator than the car, all my data logs show no drop off in boost or timing problems at low revs on WOT. But more importantly in real life day to day driving the car just pulls consistently from 3k rpm+ without any problems and out drags my mates E90 M3

Cannot be bothered to chase it up, just was interested in what total power output is, this was done as part of oil service. Will get it back on the dyno when I eventually swap out the OEM turbos, but that wouldn't be for a while yet....and I'll pay more attention to the graphs
