Just did a rebuild and turbo kit install. Started it for about 20seconds to make sure everything was hooked up right before I get everything situated for tune. Oil pressure was reading like 80psi though. Does that sound right for a texas speed ported ls6 pump?? Granted.. this is a fresh build and only a 10-20second cold start up but just curious.

That's normal for a cold start.

Should drop a good bit warm. Mine is 75ish cold and at warm idle around 50, once it gets fully up to temp it's 38-42psi. This is with German Castrol 0w40 oil.

Same oil pump? Bone cold start before with my ls6 oil pump after my cam swap was 60psi and after fully warmed up driving around for a while would drop to 25 30psi. This obviously is a brand new 10 second startup from a engine that's been in pieces and cold for the past 3 months hitting 80psi. I will see what it is warmed up once I get my tune done and actually wonder.

I figure if it drops to 50-60psi warm, I won't worry about it.

Mine was from Lingenfelter but still a ported LS6 with a higher pressure spring or whatever.

Oil pressure, especially on a stock pump, is going to be 90% dependent on the engine tolerances and the rest on the oil thickness. Seeing as how the engine is not how it came from GM, I would first look into its specs and ask what sort of oil pressure you should be seeing from the person who put it together.

I wouldn't expect the LS6 pump to be any different than stock, but I would expect a newly built engine to have different clearances. So you need to look there first.

But 80psi on a brand new engine cold is not that far out of whack.

Roger, I'll wait and see what it actually is warmed up.

Sensor is bad. That explains it. lol
