I've read this several times over the years and have never had that problem. I have about 1/4 turn from 15psi to 18 psi. Mine is in dual port with a Tial 38mm.

I have never experianced it but I have heard about it. The resolution on the valve or something like that. It seems to be more of an issue in a DIY build with hardware store parts, I think.
