I'm spiking 80psi-ish (oil pressure) running hot when I get on it. I believe I have a -4 (maybe -3) line going to my Precision SC-61. I think I should run a restrictor in the line considering the high pressure. I was thinking about this one

Anyone here running a restrictor on their feed line? What size?
