So I have 3 fox air pumps. 2 used standard ones. One brand new H.O. pump for the evol add on's I got done. The 2 standard pumps show identical readings. The H.O. pump shows 30 psi less. So if the standard pumps show 90psi, the H.O. pump shows 60psi. I noticed these differences a few years ago as well between these pumps (not the same ones).
Anyone use a different brand of pump?
