I don't understand this stuff 2006 Mustang GT when car is cold or hot it'll have 50 lb of oil pressure when I go to accelerate the oil pressure will drop about 4 lb and then pick back up to 65
Are you running aftermarket gauges? In my case my oil pressure gauge will run ~75 lbs cold and then down to around 30 lbs warm. My gauge also tends to jump around some but not that low. Maybe something with the gauge or sensor. You might try replacing the sensor/gauge if it keeps up. Otherwise, I wouldn't worry about it unless it stays low.
