12 valve fuel pressure?
 

What is the best fuel pressure to run on my truck? See add ons below, stock turbo.

I think youd probably want 35 psi. What kind of psi is your Airdog capable of?

the air dog 150 for a 12v is set @ 30 psi.

you can order an upgraded spring that will boost fuel press to 40 psi but It will not make much of a difference in your case.

When i put my air dog on they said it was 30 psi but when i checked it it was 12 psi and all of the way up was 35. I backed it down cause all of the way up it smoked alot and had a lot of turbo lag. Now that its back down to 30 it dont smoke but i dont think it runs the way it should.

Hmmmm...
We just chatted about this on another thread somehwere else.

30psi is fine and will do what you want.

I run 50psi with my FASS and from what it used to be at 24psi to 50psi there was no power gained at all on the dyno.
