I am sure you can tweak somethings here and there, but since you are on stock injectors still there aint that much room to grow in terms of hp, upgraded turbo too or no?
 
or a pocket logger of some sort to at least check for knock. afc is mainly used with high boost levels and larger injectors to fine tune. your ecu should be able to take care of your engine perfectly fine on its own. you could lean it out a little bit to get out of that super conservative target af/ratio and be near the 11:1 mark but you will need to monitor that with a wideband o2.

you dont need an afpr with a 190, however it is required for a 255.
