Search is broken so pardon the repeat.

At what alky pressure switch does the switch close on Razor's alky pump assuming it's still set in it's factory default position. Put another way what alky pressure does the light on the controller turn from red to green.

about 30psi

Actually we set them to 50. But dependent on the spring pressure, temperature, etc. Since the pumps pulse at lower pressure, its more like a 45-55 psi range.

That helps too. I've seen the pulsing going on. When I was playing around at low boost. Included if anyone wants to see what it looks like

Why the spike so high in pressure when it activates?

Your not using my controller correct?

Just add extra alcohol to make up for the lack of fuel.

Easy

I found it (the low pressure examining the log) Plus the base FP was a little low. I was trying to figure out why the ISAC was pulling boost.
