Happened to me before. Bolt sail and plunger orings needed to be changed to add more resistance. In my experience, the NT bolt system likes tighter fitting orings. Try this and see if it works. Hope it helps.

I just started noticing this. The manual and dye techs both say the nt11 needs to operate at 120-150psi, which I obtain by green insert, green spacer and operating perssure at 125. However I know that for the longest time I used just the green tip insert with no spacers operating at near 105. I dont know how to fix it back. Ive changed all the orings with no luck. I would have thought that the orings would have broken in but doesn't seem like the case for me. However there is a notable increase in sound and the shot is a bit harder too.

Keep it the psi at 120/125 & Add the small spacer. It should drop your fps. You could also use the blue bolt flow insert. Try one or the other to see which works for you.
