I'm planning on installing a wideband o2 and tuning with my safc,(can't afford dsmlink), what afr's should I aim for to get maximum power??

-stock 14b
-550 injectors
-2.5" turbo back
-uicp
-mbc
-safc
-k/n filter
-rewired 190 fuel pump

I'd keep it below 11:1 with your setup.

So the lower the number the richer the afr?

Isn't 11:1 too rich?

nope, the lower the number, the richer the ratio

Stock is somewhere around 9:1, 11:1 is the highest I tune for on pump gas.

Is there any recommendations going over 12:5 at all...
