High cold oil pressure, low hot oil pressure..?

Factory spring is in the front seat, white spring is in there now with about 4 full turns. That got me around 10psi over the factory spring with as much adjustment as it could muster. Stock spring with no adjustment got me max 27-30psi. I'm definitely bleeding pressure somewhere.

3.42 gears, th350, 27.1" tire, 70 is the limit, 80mph to keep up with traffic.

 

Same gear and near same tire size as me, I’m 245-60-15, I turn 3200/3300 @ 70 mph

 

i mistyped, 26.1" tire, 235/60/15 for me.
