I am not an expert, but from what I read here and there about 996 era engines, location of the oil pressure source is crucial for the correct reading.
Speculation as which one is the most correct...

However, from other cars I used mechanical or sender oil pressure gauge, the values were about 60-90 at cold start (depending on weather - the colder the higher, of course..., so winter, -20 C was 90 psi). Hot, idle, down do 10-15 psi, any speed increase would jump the value right away.At normal driving anywhere (2000-4000 rpm) 20-50 psi.
