Hi all, can anyone give a heads up, I have been running my hfs4 for a while now on a .9 jet on my skyline, I put in a 1.2 jet so I can get a retune etc etc, I was trying to set it so it started to spray when I want (5psi) and reach max at about 16psi, but as soon as I started playing with it, it continually tripped out, I set the SC, moved the WL full anti clockwise and the WH full clockwise. So I cant work it out, all iv played with is the thresh and the gain, and it was tripping in the way that it stops spraying all together. Help please
