Any one interested in the oiling mods I did?

There are some similarities in your example but the big difference is one of pressure. The air in your Ram is not a 60PSI system, it's almost no PSI. As you noted, as soon as your imposed a little backpressure, the airflow evened out. The amount of backpressure you imposed was very small, too.

Imagine if you changed to a 35HP air blower so that it would put out 60PSI even with the driver's side wide open. The passenger side would blow all kinds of air. That's because there would be 60PSI in the system and the air would be seeking a place to escape. It's not going to 'work' to maintain 60PSI out the driver side when it can just blow out the passenger side.

I disagree because you are focused on pressure. The issue with #4 main is only a problem with a high volume pump. The extra volume creates a speed issue. Even a pressurized system moves oil. If the rate of travel is to high, then it becomes possible not to efficiently make sharp turns. I beleive that is what my dash example shows.
Another example I will share with you is that I installed a shift kit in my 47re truck. The instruction said to drill certain passages to a range of size. I went on the larger side of the recommendation.
After the initial road test I though the shifts were too firm.
I called trans go to get a new separator plate from explaining that I wanted to reduce the size of those holes to soften the shift.
There answer to me was that doing that would reduce the pressure at the clutch pack. Explain that when there would have been no system pressure change. Explain how the boost vale in these trans
Increase lockup pressure to a higher amount than system pressure.
I had a pressure gauge on my trans. System pressure was around 90 psi. Upon lockup the gauge goes to 135 psi with system pressure at 90. It just is not that simple imho.
