Tuning a Proform/Holley carb, what parts and tools?

Punp is a Carter M6902 mechanical.

Other than a little sloshing from the car rocking side to side with the cam lope, fuel level looks very stable at idle.

I keep wondering how to route a fuel pressure guage , even temporarily, that I could have someone watch at WOT?
