At the risk of being flame-barded, what psi could the stock injectors (without going above 85% duty cycle) and/or fuel pump handle?

Having said that, running 440cc injectors and 6 PSI, what type tune to go with? (I know this should maybe go under tuning but I'm not going to make multiple threads for related questions to FI)

After reading for a few weeks... I'm just confused, Most people I know who are FI (few subaru legacy GTs and WRXs) always have used Cobb, but apparently they are done tuning the 350z? But if I'm not going to ever increase the boost, is it still OK to use?

I've heard some like the Apexi SAFC or the newer Apexi Neo, but it does only A/F and not timing?

Would it make more sense to just go with an osiris or other reflash?

EDIT*** its a 2004, automatic

Thanks for any info.

 

you got a lot more research to do. Id go with osiris or utec. Cobb doesnt support the 350z anymore.

 

Stock fuel system with no mods? Zero boost.

 

Exactly...stock injectors are tiny. With a fuel return system and lots of fuel pressure you will be able to use them with FI...but you might as well just get larger fuel injectors.

 

It is best to do the whole fuel system on top of your E-management. Pump, reg, & the injectors. That way you have it all ready and tune it all at once instead of retuning later finding you needed another part.
