can i run no afm with it?

no, unichip will only get you so far and limited to one tuner in perth (tim slako) top bloke but average intercepter, better off with power fc or if budget permits link/autronic/vipec

if you end up replacing the o2 sensor don't go to subaru, go to petroject in ozzy park and get bosch part number 2269013255 and swap the plug for your current one (these are about $150 opposed to subaru genuine $600ish) & they are the exact same bosch sensor

^^^ EFI Automotives in Balcatta also do replacement sensor kits, but definitely give them a part number
