From what whipplem104 is saying, it sounds like Dieselmeken has started doing what Myna have been doing for a long time regarding the camshafts and pump timing. From Myna you get a choice of old vs new style camshaft and 7mm vs 8mm elements. So four possible setups depending upon how much you want it to nail etc at idle, and the desired power (fuel) level. And the timing is now 20 btdc, rather than after.
But I am surprised if you guys in Finland/Sweden/Norway do not know this already :-)
There is obviously a lot to the injection duration and the cams help with that, as do the elements. But perhaps these cams are out of other pumps and need to be timed differently because this is not the original application of the cam itself.
