The problem with turning the pressure switch up on a jet pump is there is a fine line between keeping the pump running as long as you are using water, and getting the pump to shut off when you are not using water.
That is my experience with Self Primers but not Jet pumps.
I have it set so that it takes about a minute to shut off after a large extended water draw. Basically a hair under 60psi. I have accepted the fact that I need to check the system every couple of weeks and tweak the on/off settings until I have time and $$ to do a full system upgrade.
