Did you tune VE using a wideband?
go to ECT spark correction and zero out the values from 32*F to 158*F and 0.08g to 0.54g.
change the idle underspeed and overspeed to +- 8*
copy your high octane...

Use the scanner to play with the timing, remove timing by a couple of degrees and play with the idle adaptive spark control; the overspeed and underspeed spark control. other than that you cant do...

you need more timing for, somwhere in the 26 degree range. I have a 239/244 cam installed and it liked 30 degrees.
From 400-1400 rpm and 0.08-0.28 make it all 26 degrees and feel the car, you might...

Pull the O2 sensors, shake them and hear if they make some rattling noise, if yes then throw them in the trash or you can do as Brandon said.

Try increasing the airflow final min by about 15% and run it in open loop, set afr to hit 14.7 and disable LTFT. Can't do much without a log file.

Just go with deatshwerks injectors and save yourself from the trouble. :)

LTFT seem to be high. Can you post your tune? Have you done any mods to the vehicle?

Sounds right, but I would go just a bit rich just to be safe. Aim for 14.5. That's what I'm doing to my car. Running in SD will make your life a lot easier rather than MAF. Is it your DD?

MAP sensor seems to be waaaay off. Check it.

Just make a new graph for it and plug in the values for rpm and cylinder airmass.

Yup, no Inj duty cycle at all!!
