Just curious as to how the stock turbo psi is calculated.

I assume when talking psi on the stock turbos we are talking about a combined total of Psi 8-9psi.

So again I assume this is 4psi per turbo which seems very low and bumping each of these little snails up to 8 psi + should not be a big deal as long as they stay within the efficiency range.

My point and question is are both turbos only pushing 4/5 psi?

Thanks in advance.
