With those injectors, I wouldn't go past 10psi. I'd recommend keeping it at 8 or below to give yourself a little safety net. 10psi on S injectors on a ZE is usually in the 90-95% duty cycle range making good power.

Cool deal, Ill tune them fior 8 psi at first then go from there.


So the internals can handle 10 psi safely?

I ran 10 psi on a DE with millenia inj. In order to do so you will have to adjust the fuel pressure to
70 to 80 psi to keep the duty cycle out of the red. This is not the best way to force more fuel into
the car, obviously bigger injectors would be. even at 8psi pf boost you will have to up the base fuel pressure to
something like 60 psi to keep everything ok.

that safe question is going to be different for every driver. if you're going to be boosting in 5th gear,
nothing seems to be safe.
