Injector/ computer question
I have a zpi stage 0 with intercooler upgrade. I have enough money to buy with injectors or a computer. if i buy just injectors, can i just turn up my boost up? or do i need the computer?

Well you cant use injectors without fuel man, so id go wioth fuel man or just save till you can buy both, with stock injectors and fuel management you can push the injectors to over 80% idc and run 5psi or less safely, anything over 5 psi and the injectors will be maxed. Im currently "borrowing" a friends 410cc injectors that come with the trd supercharger setup and they work great for 6 psi, although ill be going with 700cc's soon so i can try my hand at making an e85 map and seeing if i get the same impressive results other turbo cars have achieved with e85.

ive been running 5 psi with no tune and stock injectors for about a year. If i buy Greddy fuel system that comes with the 440 cc injectors, can i run 8 psi saftly like it says?

Yea you could put in bigger injectors, but the tune will be off, and will probably be running rich. So its not worth it, unless you have a piggyback/standalone with it.
I say get the AEM FIC over the Greddy Ultimate.
But if you must get a greddy, i'd say go for the ultimate.
440cc injectors are fine, but if you plan on boosting more in the future, i'd say go with something a little bigger. But it'll also cost more =p
If you're running an external wastegate, just swap out for a higher psi spring. Or just get a boost controller.

I went straight to 800cc injectors ^^

lol i was looking at going with 700cc injectors, im "borrowing" my friends 410cc trd injectors at the moment on psi and they do great but im planning on going to 8 psi and want to be able to try to make a map and run e85, all the other turbo people have had great luck with it due to the high octane and low combustion temp, srt 4 guys said they can pull 4 deg less timing, run 2-3 psi more safely, and produce 10-20% more power. Only thing is stoich for e85 is like 9.6:1 so youll need approx 33% more fuel.

I have a full Greddy 18g kit, i have been running stock injectors, no FIC, no gauges...just bolted on the turbo and go
After the first couple times of boosting it I found i get fuel cut at around 4k RPMS. So now im staying away from that boost.
Im getting tuned next week, new injectors, and installing FIC tomorrow.
