Question PFC settings and cold start?

In my quest to fix my cold start issues once and for all I may just shell out the cash to but a new IACV from Japan.

Before I do so, I was wondering what else could be contributing to cold start issues. Since mine have become progressively worse since my tune I'm wondering if either the PFC setings or new 650cc injectors are to blame.

Injectors are unlikely since at idle (warm) and under full load everything is smooth and it makes plenty of power.

Next is the PFC settings. What does everyone use for idle settings/ ignition advance, etc? I may need a tuner to reserch this a bit but wanted feedback from those who are not experiencing cold start issues and are on a PFC/ EJ20G combo (all ONE of you?)

I checked plugs, they are fairly new and look good. Have 04 STi coils- check, will replace the fuel filter JUST in case.

Thanks,
-Mike.
