Looked at your logs. Two areas jumped out at me:
1. Your ign timing is VERY low when its super lean, like 2-3 deg. Any idea why?
2. I'm looking at your inj timing, and for starters your Normal table shouldn't be small like that at colder temps. It should be at least the same value as the higher temps.
Also would you add the inj pw for B1 and B2 and shoot us another log? That way we can look at the inj timing, PW, and RPM and figure out if a bunch of the fuel is going out the exh at ~2,000 RPM. After plugging your inj timing into the spreadsheet I posted on the inj timing thread, it looks like you'll be close.
Also remember that the 0.050" lift events are not the same as "fully closed" for intake or exh valves...
Attached is an image using your inj timing and inj pw that I logged (~4 ms). Same inj you have, bigger cam, smaller displacement. So it isn't apples to apples, but it does show where your issue may be coming from.

Notice how the SOIT (pink line) drifts down toward the EVC link (orange). So at some combination of RPM and inj pw you'll be loosing unburnt fuel out the exh. Especially when you look at the 0.006" cam events.
HTH,
