Getting some upgrades done on VF ssv ute 2013 model. Mods including cam,rockers,oil pump, twin row timing chain, balancer kit and heavy duty clutch.
Having trouble with oil pressure. At idle there's pressure but once revs go up pressure drops. Have put new pump in/out in/out without any results. Any ideas would be appreciated. TIA

How are you measuring it?
What are your oil pressure specs each 500rpm increment? (from an external gauge)
What changed before the oil pressure went bad?

Take it back to whom ever built it because something isn't right.
