I've been having similar problems, but mine only drops to 50-52psi at WOT, but it does it every single time. I'm trying a new regulator soon...if you search about this problem under my name, you'll see my many questions/complaints.

Have you changed your fuel filter lately? Cover the basics first. Lots of people forget to change them.

If you are talking to me, yes...I run a Canton fuel filter, the line running from the top of the tank to the filter is a -8AN stainless braided line (i.e. no kinks), FAST fuel rails up front...you name it. This weekend will be the start of my front mount regulator install.
