the regs are supposed to be balanced (in other words, you shouldnt have the inline at 350 psi and LPR at 70, or the LPR at 110psi and inline at 200). so if the regs are far enough out of whack relative to each other, your velocity will drop. so, say you have an aftermarket valve, so your inline is at 225psi, and the LPR is at 80. they are pretty much in proportion to each other. but if you continue to turn the LPR up higher, eventually the pressures wont be in proportion, and therefore the regs will no longer be balanced, so your velocity will drop as you turn up the LPR rather than increase. does that make sense?
