The things that worry me are cyl4 timing corrections and especially the HPFP actual pressure being completely off. The LPFP is falling off quite a bit as well. The boost is sporatic as well and spikes quite a bit (see the graph to the right of the log).
Does this mean the HPFP is going south? I think it was replaced last year according to previous owner.

I highly recommend grabbing another log with traction control COMPLETELY disabled. There are a couple things as far as boost and timing going on that are goofy, however the traction control system can trigger some weird things to happen to timing and i'm about 95% sure that TC was the cause of the boost issue.
The fuel system looks to be unable to keep up, the LPFP pressure dipping below 50psi isn't a good thing. The HPFP is also way undertarget. If i was you i would try grabbing some logs and seeing how it looks on straight pump gas.
