Power FC Default Boost Pattern?

I probably should have posted this in the Power FC section, but I think this part of the forum is much more active.

So I've searched and couldn't find any references to the Power FC default map boost pattern. Right now, I'm running 12-5-10, and that 5 at the sequential transition is awfully low. I figure it's a boost problem of some sort, but I wanted to see if someone could confirm the default Power FC boost pattern in order to gauge just how far I'm off.

The effective mods would be:
-'99 spec turbos (sequential)
-Blitz SMIC
-HKS Ceramic coated downpipe.

I still have stock intake and exhaust (with the exception of the downpipe).

Any insight would be greatly appreciated. Here's the accompanying Dyno sheet where you can see the large drop off during the transition:

You should be seeing a regular 10-8-10 pattern. The dip during transition is not normal for the PFC. However, the PFC doesn't do the most outstanding job controlling boost, so you might think about aftermarket boost control in the future.

Check out ye olde troubleshooting thread below. My guess is the turbo precontrol is malfunctioning, essentially preventing the secondary from prespooling.
