Oil Pressure going past 400kpa (58psi) after recall

[SilveradoRST]

I recently had the engine oil cooler lines recall done.  2019, 5.3, 8sp.  Before the recall, the oil pressure would fluctuate between 200kpa (29psi) at idle and 400kps (58psi) when driving around town or highway, which I know is normal.   

 

Now, I notice my oil pressure likes to fluctuate between 400kpa - 450kpa (58psi - 65psi, a tick past straight north) when driving around town, but settles to 400kpa (58psi) when on the highway.  Still idles at 200kpa.  I read that 65 psi is still an ok range.  No towing, empty bed, not sending it, in all scenarios.  Oil level seems to be ok.

 

Anything to be concerned about to take back to the dealer?  Anyone else going past 58psi just driving around town, not towing or hauling?

Canada and Alaska only and it has been out for awhile.

29 psi at idle?  Must be fully warmed up?  Cold, my pressure is at the middle, and if I go above 3K on the RPM when cold, pressure shoots up to 80psi?

 

When idling either in gear or out, when warm, yes, around 30 psi.  Driving, 60-80

Thanks!  This is what I was looking for.  Yup 29-30psi idle when fully warmed.  On startup first thing in the morning (summer), it shoots up to 500kpa (72psi) and if I drive it right away, it stays there and slowly works it's way down to 400kpa (60psi) after 10-15mins depending on how many stop lights I run into.  Never paid attention to the gauge until after the cooler lines were changed, so I didn't have any reference points.  Looks like I'm operating within normal ranges.  Thanks again.
