The pressure on a 2013 ZL1 (LSA) is between 32 and 40 psi; 32 at idle, completely full (7.6 L of oil).
On the track it temporarily dropped down to 25 psi after driving it hard. I'm running Mobil1 5W 30, but will change it for Mobil1 5W 50 again come next oil change.
I change the engine and differential oils before and after the track, as per the owner's manual, so I was running on fresh oil which only had about five hours of normal highway driving on it before the track. I hope that you find this information helpful and wish you the best of luck buying a ZL1. They are an incredible joy to drive.
