OEM was shurflo 2088-422-144 - 30 psi inlet, 45 shut off vs 55 for the 4008 as you mention. I've done a little trial and error on setting the pressure switch so not sure where it sits at the moment. What would be the consequence of going to a higher rated pump?
The 4008 is the recommended replacement for the discontinued 2088 model.
The higher discharge pressure is what you are not use to ......how it sounds/reacts when pump stops
Course.......messing around with -adjustment- can result in HIGHER pressures. Did you have pressure gauge connected when adjusting?
Pump has an internal bypass which starts opening at 40# and is fully open at 55#.....unless you changed settings????
