wow... dwell seems awefully high? I have mine on 7 (28 clicks in the old Virtue board)
Operating pressure always at 135psi region.
Lube with either Dye Grease or Monkey Poo (which ever I have in front of me then) and applied enough to make the oring and bolt look wet.
My NT doesnt seem that loud any more compare to before... maybe it got better? maybe I got used to it?
all it matters is that it shoots consistent and doesnt fail on me.
