It should go to 4000 in neutral and while running in gear

(Except if tied to a dock
then 90% of rated RPM is the magic number)
As for the new high pressure pump not delivering the RPM..?
Is it overhauled, clean, etc?
Did you check temp on each cylinder? (Not a blocked fuel
line and a dead cylinder or two?)
manual should explain adjustments. Sold my boat with the 4-108 3 years ago and the shop manual went with it, otherwise I'd look it up.
Curious to what the problem turns out to be.
