Default 14.7 AFR Possible on Turbo IS300?

Hey guys. I am having a hard time tuning the idle on my is300.

I am using an AME V1. RC440 injectors.

Car idles well enough. It does misfire sometimes, but usually not enough to throw a code. My AFR's are around 13, but that is still super rich for my taste. If i add any more fuel idle gets worse.

If anyone has had any luck leaning out their idle please tell me your secret!

How much timing are you running?

I had no issues tuning 14.7:1 and 18-20 degrees of timing.
