Default Oil Pressure guage twitches

I have a video link below that shows what it does. 9 months and 6k on a new build 2000 LS1. Already replaced the sensor and it seems a little better but you can see for yourself. It's scaring the crap out of me.
Ideas?

Clean your grounds starting with the negative battery post and including the grounding points on the back of the heads - star washers are your friend.

Thanks for the replies. I will definitely check the grounds. I was scared I had an oil pump failure. I've been afraid to even start the car

Mine has done the same thing since i got it 90k miles ago. I recently put in a new ls6 oil pump during my cam swap and it still does the same thing, so i dont think it is the oil pump.

Mine has the same thing since I put a new switch in. Grounds would be a good place to start. I'm too lazy now days to look.but now that I got my AC fixed ill look into the cause and let you know my results

The factory guage is junk get a aftermarket guage and you will see what your oil pressure really is.
