anyone?

mine pops 60-70 and drops to 20ish when hot

just dont push it when it's cold, the oil presure can get so high

Yea man, oil pressure for me on my AEM digi oil press gauge was:

70-85 when cold (driving and idle)
45-60 when warm driving and driving hard IIRC
12-20 when full warm idle.

Seems low, but there is barely any load on the motor. I ran this AEM sender to a aftermarket oil relocation kit as well, so the reading was still very accurate.

Oil is a lot heavier when cold (prior to starting it) and needs more pressure to move it around. When it is at full operating temperature, it lightens and takes less pressure to move it throughout the engine (increased flow rate), which is why you see those changes.

Give a look - next time you change your oil, try changing it without running the engine a bit first. You'll notice how slow it drains out and how thick it looks.
Then, on the oil change after that, run the engine for a little bit to warm it, then shut it down (not too hot or you'll burn yourself). When you go to drain the oil it was seem to "flush" right out of it a lot faster. Manuals mention to warm the engine a bit when changing the oil because having the oil itself be lighter, it'll remove more of the older oil and won't stick to the walls inside the engine.
