Oil shouldnt matter here, especially once warm...then its 30w, which is fine. 10w is at startup.
The way multi viscosity oils work is that the first number represents the oils thickness at startup (or cold). The second represents the ability to flow (or viscosity) once the car is warm. The lower the number the closer the viscosity is to the same consistency as water. I have run both 0-30 and 0-40 without issue. Your 10-30 will simply be a little different (thicker) at startup temps. Oh, and on the Baileys...I dont think they are worth it, 710Ns for sure. I have had a set of Baileys actually fail.

Something is not right. First off, that boost spike on throttle lift is not normal
Like Jordan & Mike said, get 710Ns.
Your MAF readings look OK for the temps...I generally saw a little more flow at 80F than 261 g/s, but its not unreasonable. Your FATS times are sloooow, though. Definitely a statistically significant difference from a *healthy* GIAC X car.
The 02s are definitely showing that something is wrong - they do NOT look normal, given the values I & others see on GIAC X. There is a kink in the 02 curve at 6k RPMs. Its possible that a small leak is showing itself under high boost and causing the mixture to richen up. Its a stretch, but small leaks can do weird ****.
My recommendation would be to pressure test first. If everything looks peachy, see if you can duplicate that kinked 02 curve. Don't try to lemmitweak anything until you get your car running properly.

Don't know the version you have, but boost ramp up (initial spike) doesn't
look good. All my X logs (pre MBC-only) look much different - A stronger initial spike. See pic poster (w/o MBC in title).
