Oil pressure on 6.4, what is yours, how many miles

30953 9
I just bought my 2015 SRT 392 few days ago, looking at the oil pressure gauge, fully warmed up at idle I have 31 psi, down the road doing 75 mph I have 55 psi. Fresh oil change by previous owner.

My car has 50k miles

Like to compare to what others have in their 6.4 hemi.
