Good news bad news...

Got a tune today after my cam, intake and header install... 410hp/396tq...

Not bad...

Bad news is... I'm not sure why I have such low oil pressure at idle. 23 to 25 psi.. When I mash it is up around 50 psi or so.

So does anyone have any thoughts?

The guys at the dyno suggested I try using a 10w-30 oil...

?????? HELP!

What were your oil pressures in the same conditions before the cam install? Did you install a new oil pump? If so, which one? Did you install a new o-ring and install it correctly? How many miles on the car? Seems that higer mileage LS1s typically show mid-to-high 20s at idle when hot.

What he said above! but what oil are you running anyways? How thick

No, totally two different scenarios as far as oil pressure... I installed a new LS6 oil pump.

Yes,at a hot idle the car is between 22-25 psi

I'd say you messed up the oil pump install via a pinched o-ring. A LS1 w/ that few miles and a fresh LS6 pump shold make 30ish at hot idle in the summer.

I really think it should be more than 30ish at hot idle... either way thats not right, i do agree it is probably a pinched o ring..

yup thats low for hot idle. def take it apart and re-verify the o-ring is not pinched. there are several good techniques on this site and other corvette forums how to install the o-ring without having to 2nd guess if the o-ring is seated properly.

Awesome, thanks guys! I just wanna go fast! haha

Well go fast after you find out why you have low oil pressure . You don't mess around when you have low oil pressure that is what can cause premature wear on your bearings, while also your running the risk of spinning a bearing.

Sorry but you need to take the front of the motor back apart and get a new O-ring and lube this one really well before you install it.
