Dave,
I would go back to your engine mechanics and ask them to check out your
density controller.  Since you make rated T.O. power it isn't out of
adjustment but, as it sat for eight years, maybe it has a hard diaphram
inside, or stiff o-rings which are causing your problem.
Truthfully, I don't know if they can check into it at the shop level.  You
may need to send it out for a bench check at an overhaul facility.
Assuming everything else on the engine checks out and you have no problems
with the pop off valve or leaks in your intake or deck pressure system,
that's where I'd go looking.

Oh, does your fuel flow change as the manifold drops off?  What is the rated
topping (critical) altitude for your engine?
