tyFlow internally stores vert velocity data in map channel 20...technically putting a modifier on top of the mesh doesn't destroy the data...but it does prevent the renderer from being passed that data properly (because tyFlow itself has to do it, but when there's a modifier on top the direct access to tyFlow data is broken).
So try this (to retain moblur):
Put your selection/deletion modifiers on top of your tyFlow and then create a second tyFlow with only an Export Particles operator. Add the first tyFlow to the Export Particles operator additional geometry rollout, then export to tyCache and render as instances....and see if the moblur comes through that way. I believe it should.
I haven't looked at the code, but it's possible that the only limitation to that method is that the vert velocity data that gets baked in only gets baked in during tyCache export (I can't remember)....so if that setup doesn't work, just do an intermediate tyCache export as well. So try tyFlow->tyCache->add mods on tyCache->re-export cache in a second flow.
