Sorry didn't read that on original post. I have heard some fast cars using the same size return. -12 in and -12 out.
Also on my Olds wagon I'm Magnafuel 400 with -10 and their regular with no return and only get or down to 7psi. The -6 let me get down to 3 psi but I I raised it to 4.5. I was able to run regular screw out about 4 revolutions after making change.
