my vote would be to crack your injectors as it sounds like air in the system.

When I changed to the GDS 60mm/16cm in my '93 it would hardly make 12psi at WOT. Upon inspection the end of the IC was split open around the inlet where the tube from the turbo hooks in. Check the IC and boots and IIRC there was a o-ring where the tube connected to the turbo that can cause leaks.
