Hi all. Need a solid from someone with L405 SDV8 and Gap iid tool to log fuel rail pressure on the go to compare if the pressure behaves similarly to my logs. The fuel rail pressure seems to be hovering up and down like a wave while tracking the ECU's commanded fuel rail pressure. Just need to figure out if this is normal.

(edit) appreciate if I can get some feedback on the boost as well. Should it be declining as rpm goes up?
