I have the same problem but I get a knock and pressure drops to 0 once it warms up.

its really not a problem. you want a minimum of 10 lbs per 1000 rpm. as the oil and engine warm up the oil gets thinner. you can switch to a heavier oil . as long as you have around or over 10lbs at idle , the engine will be fine. i know you are expecting more for a new engine. your clearances may be a little loose.
If it has 25 PSI at idle, you're alright. But if it only has 25 at highway speed, you gotta problem.

Sounds like clearance issues, bearings or lifter bores.
