Im about to recieve some 720cc injectors.
I have an SAFC and MAFT so for fuel control/tuning i will be okay.

My fuel pump how ever is the stock pump. Will i be okay staying at stock boost on my turbo(t3/t4 57 Trim)
Or will i need my walbro 255 HP in?

Before anyone just suggests to put the pump in, i do not have a regulator to control the flow of the pump.

Any response would be appreciated.

You stock fuel pump will not be up for the job. Your just asking for it if you run that turbo on that pump. I blew my motor with a walbro 255 having a 60 trim at 14 psi. I learned the hard way lol. Of course I had stock injectors thats why, but injectors wont do anything if your pump cant flow.

Car actually ran fine with the stock pump.

No problems. I just had the need to up my boost to 20 psi so i purchased an AFPR

But as long as I kept the boost at 12 psi i was good.
