injector and tuning help

My mods are sti turbo, cobb access port, 3" turbo back exhaust, and 850cc injectors.

It kinda goes hand in hand with trying to pass smog, but i have a feeling with the cobb tuner, the 850cc injectors are a little on the big side. I traded for the car with them already in there. I am kinda new to this area of vehicles as my other vehicles i modified was a prerunner and my dodge cummins turbo diesel. What would you guys reccommend for the size of injectors. I have a feeling i may be running on the rich side enough to where id get at least the same power with smaller injectors. The reason im wondering is cause the tuner reccommends the 565cc sti pink injectors, or should i run about a 650cc?

if your running the OTS AP maps then you need to run the exact injectors specified in the map notes so if it says STi pinks then you have to run STi pinks
