Sound like your lift pump is getting weak... Minimum lift pump ressure is 10 PSI... I'm going to garther your running stock fuel lines yet so I would suggest you think about a Big Line Kit From Vulcan Performance. http://www.vulcanperformance.com/Draw-Straw-II-1-2-in-draw-tube-and-1-2-in-pushlo-p/vpps9804.htm

Plus having a 5 psi drop in pressure is telling you the pump is not able to keep up with the demand. Baby the skinny pedal until you get your upgrade!
