Guys my valve cover is leaking some oil. What is the possibility of this or a faulty PCV causing my issue?

Interesting seeing this thread revival. I'm in a similar boat where it takes 800-1000 revs to reach boost target. The common thing I see with the two datalogs posted in the OP to mine is the ambient pressure. They both must be at elevation, and the the turbos have to work hard to hit target in the thin air. I live at 5000' above sea level, and the ambient pressure on my logs is always between 12.2-12.4 psi.

My mods on the log below are MHD St2+, DCI, stock location inlets, DPs, and CP running stock DVs. My vacuum lines are good, and I replaced my boost solenoids with Pierburgs last year. I need a custom tune, but want to look at other supporting mods, such as colder plugs and LPFP (I had custom parameters for this log and didn't includ LPFP values...) before doing so.
