SAFC II tune?

[DSM-is-LOVE]

so my buddy with a 97 GS-T thought it would be a good idea to start messing with his afc and now his car wont start/run. we have to figure out a good tune and i was wondering if there is anyone that could help us out.
it has a:
14b turbo
550cc injectors
255 lph fuel pump
stock internals
rebuilt 7 bolt head
manual boost controller

i would say we could figure it out but neither of us have a wideband to tune ourselves....so any help would be nice! thanks!
