I ran 22 psi spike and holding 19 till red on stage 2 kit with PTP ported turbo for a long time.
My mods at the time was stage 2 and walbro 255. I had no problems with it. It did tend to want to go lean at the very top of the gear (around 5500 - 600) it would go lean like 12.3 but I also had 50/50 meth injection so that wasnt too bad.
Oh, and stage 2 runs rich is you dont turn up the boost much. Stage 2 has bigger injectors (682cc). If you dont have walbro 255, you should be fine running 18psi all day long with your setup.
Hell, I ran 17 psi on a 60 trim turbo with the stage 2 injectors and fuel return for a while after my stock turbo blew up and I still was staying around 12.0 AFR with injectors at about 85-90% duty
