With an Intercooler cooling the intake charge, wouldn't one be able to increase manifold pressure over a non-intercooled installation (like mine)?  Not sure what the visor or the POH reads, but I would think the opposite of what the OP had written earlier.

Skybound, I have the same setup as your, the Turbo plus and the Mrylyn waste gate.  On mine I have to watch cylinder 2 which is infront of the oil cooler so the airflow might not be as good an there m

What procedures / steps for LOP? Figure out a power setting that is LOP and then just pull the mixture straight back to that fuel flow.  Some power settings that worked for my 220 hp TSIO-360-MB/SB:

I'd suggest the following: 0) Before flight, pick 2 or 3 power setting you want to collect data for, begin conservatively with 55% power and go up from there consecutively as long as TIT allows, such

Wait....I think I've seen the error in my ways!  As the OP is looking at or for a particular percentage of horse power that % would change based on the induction air temperature.  Cooler induction = more horse power.  So he is 'removing' .5" of manifold pressure per 10 degrees of reduced induction temperature to maintain say 65% horsepower.   

 

Only took me 10 hours to figure that one out, I'm getting better!
