I have also have Stillin plenum with A2A setup but about 2000rpm slower with my pulley sizes (checked with Vortex calculator), but with upgraded Si trim and only get 10psi. I'm also running the "standard" belts on serp and SC. Are you using the Gates "RPM" belt(s)?
I have ordered these to see if they will help with boost, otherwise I have no idea how you could get 50% more boost than me, but would love to know.
