I have stock injector right now and i want to know what is safe fuel pressure before they burn out is 7 pounds ok with stock injectors, i have the rest of the fuel system, pump, rail fuel regulater? Tell me what you think or have done(and it worked)

 

umm you dont have the boost dependant FPR? the small little one isnt gonna do much you will be runing lean with that

 

Didn't quite understand your setup... What do you have past the stock injectors as your fuel ?

Do you at least have a POS FMU ? If you are just running a stock fuel system (stock injectors, FPR, pump..etc...) After 3-4psi you will run dangerously lean.

stock injectors should be able to handle 7psi. it isnt unusual to find guys runnin 9psi with stock injectors. of course.. with an inline fuel pump and fmu at least.
