poor boost

i have a 1987 9000 turbo. the engine has 170k miles on it. i've noticed that the "kick" after the turbo spools up is decidedly weak, and when i watch the pressure gauge, it never enters the red and even begins to drop off after 4500 rpm. i've already checked the plastic hooter valve and it holds a vacuum. the turbo is relatively new (maybe 40k on it). i don't think i have a pressure leak anywhere on the intake side. i was thinking maybe not enough fuel pressure, or maybe my APC is coming on to prevent knock, any chance that it's one of these, or something else?
also wondering if anyone knows about the feasibility of exchanging a TD04 high pressure turbo off a 91-93 9000T in place of the T3 on the 87 9000T
