A side note.
IF you decide to "up" the PSI cut off on any compressor, be SURE to check what PSI the RELIEF VALVE open's at. Most are just a few pounds above the factory setting on the switch.
A highr tank PSI does nothing for adding capacity as oldred stated, It just provides more "power" for tool's like cut off's and impacts,ect.
Mine is at 130 and my cut off tool is almost useless on some cut's.
