The Kingair's torque setting is in foot-pounds if I recall correctly. Use that as your 'manifold pressure' if you will. Allow for a short spool up time as well - not much, but there is an appreciable difference.
Also, compared to the pistons that you have been flying (assumption) you will not be used to the relatively huge amounts of power that a turboprop, particularly a 200 has to offer. So watch out for that...Other than that, enjoy!
