I have a set of triple Delorto carbs that I am putting on my z and would like to know if the 4 psi from my pump is too much. I havent had any problems with the DGVs that are on it now.

Supposedly the Webers want to see 2.5-3.0 psi, I have dual DGVs.

Are you on a 2.4L? Do you mind sharing your jetting setup? Myself and some others are trying to sort out the issue, since 2 DGVs is enough for a 3.2L engine in stock form (1.6L Ford x 2).
