Wierd Oil Problem On My Built Rb26

[ReganGTS25T]

ok well heres the problem i just finished breaking it in, the engine runs fine im up to 8000 rpms not goin to go to my destined 9500rpm mark till my ati damper gets her, my oil pressure on idle and cold idle is fine cold idle 75 psi warm idle 25 psi, but i accelerate in nuetral and the oil preasure goe sup real slowely too 40-45 psi doenst go any higher its got a brand new pump.... here are my thoughts on what it could be

1 faulty autometer mechanical oil pressure gauge(but worked fine on my built rb25)

2 the rb26 oilfilter block maybe clogged?

3 oil pick up might be cloged?

here are some vids fo the oil preasure gauge

Does engine load affect the way oil pressure builds?

Oil pressure is RPM dependant, as it is driven by the Crank, the higher the rpm, the more pressure.
