Lean? I thought you said in the beginning it was running rich, but others said it's actually running lean...I can't really see the photos on my phone too well...
What do the fuel trims do when you rev it up? Sounds like it's a fuel delivery problem by your information about fuel pressure, which is consistent with system running lean. When you rev the engine also monitor fuel pressure. Better yet, check these things while actually driving to simulate real conditions.
Maybe engine runs rough under load because the pump can't deliver enough fuel for the demand? The fuel trims will show you this.
