Hi Tony,
Thanks for the helpful responses, let me try to clarify the videos;
Video 1:
https://youtu.be/lbuWbLmb3pA
Shot yesterday afternoon after the car had been sitting for about 6 hours.
I didn't touch the gas until 54 seconds into the video and then I revved the engine a few times.
Video 2:

shot this morning with the car ice cold- last start was yesterday at about 3pm to shoot the first video
I didn't touch the gas pedal at all (I was sitting in the car so I could show the gauges better):
I'm planning on first doing a full CIS pressure test next weekend to collect all of the data on the system and then I'll do a smoke test to see if I have any leaks in the vacuum. I'm hoping that will pinpoint the exact source of the issue and then I can figure out how to correct it.
