How much turbulence is too much?

OK now I have another problem with this. Shouldn't this depend on
the propeller? For example, I believe the limitation on static rpm
(for maximum throttle setting) on the plane I fly is less than the
2480 number you mention, so I would guess all of the numbers will be
different for me. However, my POH seems to show the power curves up
to 2700 rpm, and does not mention the type of propeller (maybe it's
the "standard" prop?).

If you have a PA-28-161 (or any other plane recent enough to have a
standard POH), look at section 1 "General" to see what propeller the
POH uses for the performance tables. Under subsection 1.5
"Propellers", I have this information:

(a) Number of Propellers 1
(b) Propeller Manufacturer Sensenich
(c) Model 74DM6-0-60
(d) Number of Blades 2
(e) Propeller Diameter (inches()
(1) Maximum 74
(2) Minimum 72
(f) Propeller Type Fixed Pitch

If you don't have that propeller, I'll hope that you got revised
performance tables with your STC or field approval, but I don't know
enough about the regs.

Ever since the Governor of South Dakota was killed by an improperly selected
Propeller, the rules have become very stricct in those changes.
