Pop pressure question

[charlie19]

There have been some excellent posts on this subject (especially the tutorial from Beagle) that I have followed with great interest. I have a specific question that I am hoping someone with more experience can help me with. My injectors range from 103 to 113, all below the minimum for the 240D I have, but above the 100 minimum for used injectors per the MB shop manual. I know they need to be balanced better, but I can live with the extra vibration for now. My question is: Does the lower pop pressure affect the timing and power? It would seem that the lower pop pressure would cause the timing to be advanced somewhat, but I am wondering how significant this is?
I just got through rebuilding my injectors and putting in new Bosio nozzles (thanks to Dieselgiant for the excellent tutorial). The improvement is impressive, but the old injectors were the original equipment and 2 were obviously bad, so a comparison is not meaningful. I made a bottle jack tester from the McMasters parts list that was posted by Boneheaddoctor (who gave credit to Old300D).Thanks guys.
