Running pressures:

Ambient Temperature - Approx 104-106 degrees

Idling, Max A/C for 15 mins

Low Side Before - 37
High Side Before - 250-255

Low Side After - 42
High Side After - 245

Static:
Low - 80
High - 150

From what I have been reading, the X does not typically like above 30psi, but no one seems to be recharging their system in the epicenter of Hell, haha, and I cannot find a matrix from BMW for it. I had my wife give me 1500rpm and the pressures dropped to approximately 26psi low side so I slowly added the R143a and the vents got colder, which landed me around 30psi @1500rpm (equating to the 42psi idling).

Also, from my experience the static pressures should be closer than that. So, I am interested to see what you think of those numbers, and I have a feeling that someone has messed with the system before. In the back of my head I keep thinking that it is needing everything recovered, vacuumed and the proper amount of refrigerant added to cure the temperature difference in each side. There are so many issues that I want to figure out the most efficient way to go about finding the solution (Many different things or one thing causing all symptoms), hoping that someone else has experienced this and can point me in the right direction!

***Keep in mind that these numbers are off the top of my head. I do have them written down at home.
