Is this with stock injectors (brown/orange) in color?

You will most likely want to upgrade those to 24lbers.

With 19lbers (stock injectors) you would probably want fuel pressure in the mid 40psi range with vacuum line off. Maybe even more to get a good a/f ratio or atleast help...

i'm thinking about 38psi

I would start around 40, depends on the combo, my car likes to run w/a little more f/p, I run around 43
