Oil level and condition ok? What mods if any? Also have u verified with mechanical gauge. 30 psi is plenty. Only required ~6psi per gm specs at idle.

Sounds fine. Couple things to check are is the gauge accurate? Have you by chance changed the oil viscosity or have the outside temperatures changed during this time? I honestly, wouldn't be worried but would look into the gauge working correctly etc just to be proactive about it all.

the oil level was a lil low so i added some. i did a oil change about 800miles ago with royal purple. yes its modded. different heads lifters pushrods rockers cam and throttlebody. im going to put another gauge in and check it. and i have heard that they can run off that low of oil pressure just thought it was weird it randomly decided to drop 10psi
