Your fueling seems to be all over the place at low MAP and rpm,Where is the wideband sensor located ? any exhaust leaks ?

I'm wondering if you maybe have similar operating system problem to this thread - http://forum.efilive.com/showthread.php?t=13235

also when i look at your Ben map from logs you seem to have alot of cell count hits in the 0-400 rpm row, yet when looking at the log you don't actually dip into that rpm range to often.

You really need to verify what fuel pressure you have and weather its fluctuating much esp when the second pump cuts in to enable IFR to be scaled correctly.
