-10.5 degree Timing Pull. Is this normal?

[Mussa]

I took a log for a timing pull @ 3rd and 4th gear from 2000 to 6150 rpm WOT.

As seen basically in the graph for 4 of the cylinders timing pulls were 0 for all the rpm range. However at 6100 rpm for 3 of the cylinders -10.5 degrees of timing retardation occured. At that time the specified/actual boost was 530/1645 hPa.
Should I be worried about this?

That's because you hit the rev limiter that's preset in the ECU; therefore for engine protection, the ECU pulls timing.

Hmm, but i've hit the red line a few times and no timing pulls occured. Only this one.
Maybe it's about the boost, the actual boost exceeded the specified quite alot.
