Default Question about fuel injectors

I have two subarus and i want to change the fuel injectors between the two. the first one has sti 08 pink injectors , and my other subaru has stock injectors. Is it okay if i change the two without tunning? the first subaru has cobb access port, and the other subaru is just plain stock.

Uh...we need SIGNIFICANTLY more information than that. Like, what subarus are you talking about? We don't even know if they're both top feed, much less if they run the same injectors stock. That's akin to saying, "I own two cars, can I swap the wheels between them?"

If they're not the same exact injectors, then no, you can't swap them without tuning. Even if the flow is similar, the latency won't be, which will make both cars run like crap at idle, assuming they can even start.

So basically you're asking if you can swap 08 injectors in for the stock 2L wrx injectors without tuning, and swap stock 2L wrx injectors into a car tuned for the 08 injectors without tuning, correct?

Definitely not. Even if you could get the cars to start, they would both run horribly, and would run very dangerous AFRs in boost.
