just wondering what you guys think is safe ignition timing when running 14psi on a s14 sr with t28, 550cc, z32 maf, before i actually go out and drive it

i currently have 15 degrees BTDC which is stock

i have an aem wideband and an afc neo which i've been using for a while to fine tune my afr's, but for some reason when i put in my 550cc injectors instead of taking fuel away, i actually had to add +33% all aroud just to get it to idle at 14-15afr and 11 in boost

the injectors are nismo 550cc that plug right in and have the yellow caps on them

i've yet to do anything and just trying to get as much info in as possible

thanks in advance
