Adjusting or attempting to adjust the switch to a higher pressure is a huge wast of time. If anything you want a switch that shuts of and turns back on at a lower pressure. The compressor will thank you with building up less heat over time and getting it back up to pressure quicker. Take a look at the rated outputs of compressors the lower the pressure it is working against the higher the cfm. Or take a look at your gauge when you fill the system from empty you'll find the rate of increase in stored pressure decreases dramatically as the stored pressure rises.
