Default Standard 4x4 sapphire boast pressure

Hi all,

Just wondering what the standard booast pressure should be, as on my gauge I'm spiking at 0.75-0.8 then it drops to 0.7 then it slowly drops to just below 0.6 by 6k. Does this sound right as I seem to be down on power on the rolling road?

Matt
