Installing 1bar Spring, Ign Timing?
 

SO I am installing a 1 bar spring next weekend. Right now, my AFR's are on the rich side, immed going into low 12's when coming on boost, then all the way down to the low 10's. Also runnning a Kokeln IC. My question, and concern is with Ign timing. right now, it is set to spec, but do I need to retard it a bit before installing the spring?

No but you should use 91 octane.

yep, always do. thanks. Your headers are next.....

We have 93 octane pump gas everywhere in Florida... I'm surprised you don't where you are.
And yeah, don't retard your ignition timing it's retarded way too far already.

Not everyone has 93 octane but I think all have 91. Watch the EtOH content as CIS doesn't like it.

FWIW, never really noticed, but we have 93 everywhere here also.... and a bunch of Shell stations that also sell Eth free gas.
