hey guys im runnig a cheap t3/4 on 5psi on my stock compression b16a1 in my ef3 civic
just wondering what a optimal air/fuel ratio would be for me to tune it to ?
reading on wideband o2 sensor would 11:1 be good or maybe 9:1 ?

cheers guys

 

isnt 12:1 a bit lean tho ?

with vtec plus boost ?

also i run a version 4 link ecu , it has ignition advance but how do i know how much ignition to run cause its a start from scratch tune ...
