as of now my rev hard II kit has stock injectors, but no inline or intank performance fuel pump. I don't know how it's running now, but if I add just the pump would that be sufficient to have it run as stoich as possible, or would i need to add 310s. The problem is that I don't want to run too rich, because come smog time I can pass it easier then having to tear it all out...

you need to get inline pump or huge intank pump that can handle high psi pressures. Right now your car is probably running extremely lean. The LS can take 7-9 psi on stock injectors before it will start to run lean. 10-12psi is possible on stock block if you get 370cc and fuel controller.

 

I had the same problem.. only i had an upgraded 255 intank pump, it would run lean anyway.. Mark let me know one day that I need the inline pump because even though the pressure is high, it's the flow that's not getting into the fuel rail/injectors... an inline pump will help you a good bit... i'm nt runing lean anymore under boost....

 

At what point do stock injectors reach their limit of flow, say max 6-7 psi of boost or so with the help of an inline of course...

YOU ARE RUNNING LEAN. you need to get an inline Bosch pump or at least a high pressure intank pump. Dont even try to boost it without a fuel pump. I wouldnt boost over 8 psi with the stock injectors.
