I really not sure how that's even posiable with your set up? With the 9PSI pully you shouldn't see any inssues , especial with TPs you losing boost pressure should your only seeing maybe 7psi? In my old set up before I changed anything I was seeing 9 PSI (8 PSI Pulley) and made. 412 WHP on the Stillen injectors an stock MAFS. I change them in my chase for 500WHP. The Stillen injectors and stock MAF's will and should be good till you get near 450's WHP . And thee any leaks in the system ? We need more info?
