i'm not sure if the symptom you described is characteristic of an off-center flywheel, but as far as i know that is the main balancing issue in a swap. i swapped a turbo engine into a manual car and rebalanced its flywheel to match the old automatic stuff.

did you have the new flywheel balanced against the old one?

Yep! Same for the OM605 Turbo .. We also had to grind off 2 or 3 mm of that nose...

I have a bit of buzzing/vibration from ~1500-1900rpm any gear with light throttle input.
I can power past it, smoothed when I floor it and revs quick off boost due to upped Alda.
But, my rear main seal developed a leak within the last few months and I wonder if it has to do with the out of balance situation.
It is smooth when ripping through the upper rpm's and going down the highway (~2800rpm at ~75/80mph) so I have learned to live with it or drive around it.
This example is an 87 190Dt converted to 717.411
