Fuel Pressure Setting

[CobraR77]

I just picked up a Kirban fuel pressure regulator for my 95 Cobra Conv. I will be installing it along with my other on the shelf goodies. I was curious what I should set the fuel pressure at. Please see signature for setup. Thanks,

I'd just install it as is (should be set for stock) and tune it on the dyno after the installs....

38 or 42 comes to mind. Can't remember which though. You need to set it when you put it on.

Stock is 38-42 vac off & plugged.
When the vac is re-installed, it drops to about 32psi.

Is it 38 to 42? I thought it was a certain exact setting?

Generally it's like 38 or 39... but I've always read and seen variances up to 42.
