The 3600 stall sounds like a great choice. The drop in boost sounds about right. What are you shifting at? Those partiot springs can handle some high RPM's so you might consider winding it up a little higher to hold the boost.
Like Sharpshooter said, the AFR's are in your tune. Even with a non-progressive Meth kit, your tuner can compensate for the Meth. I imagine dailing in your tune will also make it pull harder which will make the boost recover faster.
It will get there . The D-1SC is a great blower with a ton of potential.

i think i get what u are saying move the controller of meth to start spraying 10% from 0-10 lbs and full from 11-13 right so the af could stay the same along the line right ?
