Alright, here's what i've determined from my datalogging today.
1) ECU Codes
O2 sensor bank 1 no signal
Too rich (don't fuckin ask me how)
Ign. or coilpack misfire

2) Although I coded rich, my o2 voltages seem to be way lean. For a 12-13psi run, my o2's never passed .90. When I turned it down to 9psi, i was getting voltages from .92 to .94. But even WOT my voltages were strange, like....78, .80, it kidna jumped even at WOT, which i thought it wouldn't do. That's leading me to think I need a new O2 sensor. But would anybody have an idea as to how i coded rich, but i'm actually lean??? My fuel pressures are outrageous, so I know my FPR can't be the blame of the problem.

With your O2 sensor giving no reading, your engine will run rich by default.

Sounds like your o2 is screwed. The A/F guage will be way off no matter what and the ECU will just DUMP massive amounts of fuel to compensate no reading.

Yeah, that sounds right but why am I still leaning out even with all this fuel being dumped? I mean, i'm leaning out if i go over 11psi, and these are 30lb injectors!!!

if your o2 sensor is no good, your a/f readings wont be accurate dude. such as too lean too rich on the gauge.. the ecu is dumping the correct or some extra fuel to be safe since one of its sensors 'might' not be good anymore check that out and let us know...

Yup, like the others have mentioned, if your O2 is bad, our ecu will, by default, go into safe mode (rich). In which case, your O2 reading will always be off. This is when you need to pay more attention to the EGT temp, or not boost until you get that taken care of.

Well, my EGTs are through the roof, as well. That's why I was concerned about going lean, after last firday night at the track when my EGTs hit 925, and seeing my .88-.90 max o2 voltages, i was simply thinking of the absolute worst. If I have a malfunctioning o2 sensor, and my EGTs are afterburn, then i can go *whew*, but if not, then i'm screwed...right?

Right!

Also, FYI- running way too rich will cause o2 sensors to break.
