43 psi for a 2g....for when you set with a fpr set it at 43 with the vacuum hose off

37 psi for 1g. You can switch to 43 psi if yo have to.(BTW switch what the stock presure regulator?) but normally no.

I quoted it from this link

From what I understand 37 is for 1G's whereas 43 is recommended for 2G's. I ran 37 PSI and noticed an increase in knock so I adjusted it to 43 and took it for a drive.

With the vacuum hose disconnected: 2g's 43 psi, 1g std. 37 psi, 1g auto 43 psi. The fpr's have different bolt spacing on the 1g vs 2g but I think you could swap then if you did a little filling.
