Thas was what I did.

The rules of physics do apply here. You can't have a decent, stoich idle with such huge injectors and 60psi fuel pressure. Lower your fuel pressure as a first measure and run a richer idle.

Who cares about rich idle? I got it down to 11:1 and nothing changed. I could live with this, if it could make the engine work smoothly.

Also, my other concern is that on load the engine coughs with decent rich afr's.
Why is this happening?

Could you share a log of this happening? Let's see some idle and some light load. The raw excel data, not just a picture.

I am getting suspicious about wet plugs. I'll change them tomorrow to see if it is this because the car really feels that is running on 3 cylinders.
I owe you a log of course tomorrow.
