How much boost can stock T2/T1 33PPH injectors support and at what fuel pressure?

15 psi or so at stock fuel pressure.

so, 55psi + 15psi = 70psi fuel pressure or so.

Depends on the turbo as well. Fuel in relation to air will determine the mixture. If you had a stock turbo I would think 11 psi or so would be about it.

I've got a T03 off of an 88 Shelby Lancer TII and also the intercooler and a intake temp sensor with a Stage 3 PCM from FWD performance (15psi). I'm only @ 10 psi now but I want to get it to 15. Do I need more fuel pressure or should I use my +20 injectors and cut some press. with and AFPR ?
