I know thats what you suggested, and I was going to swap it back (switched it to this when I was having all sorts of pressure issues) and there have been no ill effects at steady state the pressure stays even +- 1-2psi. If I start to have issues I will put it back. I never looked at my trims yet but when im do that will give me a better idea on what the system is doing.
