basicaly i have just completed the manual conversion but drives like crap really lean once i installed wideband

right to the questions i know the rb25 uses the cam angle sensor as apposed to trigger wheel what can we do there ?
plus it uses maf config what is the best way for me to go maf or map ?
the turbo is massive upgrade hybrid injectors are 550
also the aac how will i use that ? i understand the rb25s use startup idle valve and normal iacv.
also the ignition coil on plug but will i need external drivers ?
searched and found basic startup map and wire graph but thats for skyline stagea is different i have the pinouts for the stagea loom if that helps
any help will do thanks
