Default Fuel pressure drop

Is a small drop in fuel pressure not normal? I notice mine runs at 66lbs normally but under WOT drops to ~57lbs.

The stock pump has a filter that supposedly was maintenance free. Not sure about the magna pump?

Is the FP gauge a recent addition and now you are watching it getting paranoid or was it usually sitting at 66 and now it drops? I know most sit at 62psi at WOT. Wide Band installed?

Gauge has been there for a while but never noticed the drop before but I may have been too focused on the afr?

Maybe the regulator?
I got to get back up on the dyno soon and dial-in soon.
