Default LS1 oil pressure ??

I have noticed when my 99 Ls1 swapped GP the oil pressure is about 40 psi when cold once it warms up it's only 20 psi.... at idle it goes up once to 40 no knocks no strange sounds but it has me worried... SO should I replace the oil pump? you think its my og gauges ?

The obvious solution is to install a manual gauge.................no replace your oil pump THEN install a manual gauge so you know exactly what's going on.
