Fueling & Injection - fuel pressure regulator?

what kind are most running i did a search but all it really came up with was pressure issues
and i found one post discussing aeromotive regualtors but that was it.

im running a -8 feed and a -6 return oh a system that will produce in the 520+ rwhp so i was just wondering what some of you guys are running and where did you get them

How do yall like the aeromotive regulators? Or others? Have yall noticed any difference in driving around or at the track? I have heard both good and bad

I like mine. No problems as of yet. Of coarse I have less than 3000 miles on my new setup, but I have never heard anything bad about them. In fact, I bought aeromotive because it was recommended to me by someone I trust and has used their products before.
