The only thing that I am positive about is that *my* TBM prop of the same size as the NX was 500 rpm difference. Folks may not agree, or speculate that something else is going on, and I would probably question it myself. Except that I was running the radio and the tach.
I don't mind that they are different, and my past experience with TBM wood props on other airframes has been that they "work" very well.
Part of the reason that the tach doesn't always tell the tale, as they say

Ya know...
I bought a TBM prop also for my new DA 100 and I'm down on revs as to what i'm supposed to be getting. I'm turning around 5700, granted it's a new engine.. but I should be over 6k! I ordered the TBM thinking it was the same as the NX... I've got a Xoar on order now to replace it next week. Seems to me from what I'm reading here all the TBM props are down on Revs... Mine was also WAY out of balance, more than I've ever had to balance a wood prop before. I would send it back on their "satisfaction guarantee" but I've had it over 30 days, so I don't know if they would take it although I haven't asked either.
