Installed my new pump from Julio and decided to run a bunch of tests. My excel sheet didn't come through as I'd hoped but you can still see what's going on.
All tests were with a fresh battery charge and charger attached at 2 amps - key on, engine off. Used blue windshield washer fluid for testing

I did this for my own amusement using Julio's test kit, some hose, an air regulator and a boost gauge.
In the words of Julio, it doesn't matter what the pressure is as long as your suppressing detonation
I have more tests to share showing pump pressures with changes to the PAC initial settings.

In this test, the initial setting in PAC is at 11 o-clock - points at first "i" in the word initial in box. Columns 1-8 represent controller setting and pump pressure is below. Boost is in the first column.

Listed here are the changes to pressure by changing the initial setting in the PAC. Above the knob is the printed word "initial". I reference the knob as on a clock. 11 o-clock, 12 o-clock etc.
