An unmodified boost pump? 
Boost leaks fo' shizzle. Should be 12-14psi standard. Any idea how old the manifold gaskets are, or if the manifolds have been off at any point? Check all the nuts are done up tight for a start.
D seal definitely seated correctly?
Is it smoking on boost? If not, could be a fuelling issue
