injector help

[chumleyj]

I have the 480cc sti yellow side feed injectors. I was just wondering if they will work without an air/fuel controller or not. Or can I just put them in and they will work with stock computer. I also have the vf39 turbo if that makes any difference. someone please let me know. thanks

if you're gonna run bigger injectors and a bigger turbo, at some point you're gonna need engine management.
