SAFC Needed for Hahn STage 1?

[InfamousEclipse]

I heard you may run really rich and would need a S-AFC to lean it out with stage 1 for HRC? Is this a common problem>? Do you guys feel a SAFC is needed right away?

No you don't need it. It acctually could hurt more than it can help by advancing timing. So if you get it don't lean a lot with it.
