Over all your running very lean. You should be somewhere in the neighborhood of 128 for the BLM. The INTs show that the computer has fully learned that you need more fuel but since the BLMs are soo far off from 128 I'm betting the computer is having a hard time giving the proper fueling. If you still have your afc I would bump everything up 3% and see how close that brings you. Or if your doing it willwrens way you definitely need more fuel pressure.

If I bump up the AFC 3%, it wants to idle at 2500 RPM. I'll ramp it up and see what happens.
