I finally got my top feed conversion done but theres a problem. I have to keep my fuel pressure at like only 15 to 20 psi or the car will be so rich that it will not run and wont even start. I know the easy answer to this would be to turbo it to get more air for the fuel but i want another option if there is any.

I'm confussed on your question. Are you saying that right now you're using Ford Green Tops?
Welcome to the world of larger injectors plus no ecm / pcm tuning. Even with a turbo you'll still tend to run rich as the fuel pressure will increase at least as much as air pressure increases.
Change the injector constant in the pcm.

What slowolej said is correct.
Find a size injectors that is more suited to what you're running currently. You're running very large injectors (even for some Turbo setups).
Simple solution is to just get lower flowing injectors.
HPTuners, and change the injector constant. Or you can buy my 310 cc injectors :-)

No, he cant buy your 310's. They are high impedence, he needs low's.
I know this is a bit old, but i thought green tops ARE high impendence? I found a set on ebay that i want to buy for my 01 to use with my SC reflash untill i get a custom tune. Is there a harness conversion or anything i need to know about to get them to work properly?
I ran 24lber's in my 99 sunfire for the heck of it the ford blue top ones and it ran rich. And your using green tops?
Those are rated at 42lbs at most gm pressures. Heck i run green tops in my 95 t/a with a built 391 and 6lb'z of boost.
Even though i have them maxed out at around 5500rpms and u stuck them in a mainly stock cav with no tuning. What were you on when you decicded that?
My bad you have a 3.4 swap but still what did you expect?
No edit button i seen the post was old and someone braught it back and if they are green top ford injectors as found in the ford lighting.
Then yes they are high independance.
Hi. About bigger injector, I'm running venom's that are supposed to be 15% larger, is that true or is a scam? I have the blazer fuel pump swap and adjustable fuel press reg. and lots of other stuff (see my profile if you can). Are those venom helping me? Thanks.

probably not with out a tune.
What would be a good size injector for only running 7-8psi? I have a guy who is selling a set of Ford green Top injectors for $50 but i think they are a little to big for what im going for. My car is a 96"z24
