Tuning past 12 psi (afr)
I did a search, there is a ton of info on tuning from 0-12psi, i got that down. So here I am at 13 psi with 11.5 afrs, I know u have to drop the afrs as you go up with boost, but is there a general rule of thumb?
Btw this is a build b16a, if that matters

I didnt think so, but as you go from 0-12 it steps down from 12.5-11.5, i plan on running 20+psi, is it safe to run 11.5 or do people go down even farther to 10ish?

I surely don't tune much of anything to 12.5 afr on a street car. I alway stay anywhere from 11.8-11.4 on street cars. You really shouldn't be in the 10s, that is rather rich. I would stay mid 11s even at 20 psi and it should be fine. Timing is the bigger factor.

I thought that was the change over point from USDM to JDM.
No but seriously i think you may want to look into pulling timing when you start adding boost. Whats your EMS, does it have a step retard???

I though my motor was in "jdm" mode until it hit boost with my usdm parts
Im running a step retard, and i pulled alot of timing, which i dont plan on adding until i get on a dyno. I just wanna get my afrs mint until i get dyno time. Im running crome abt2.0
