optimal fuel pressure??
 
Anybody know what the optimal fuel pressure should be set at on the airdog? I hear between 15 and 25psi!?? Somebody want to narrow this down!

15 psi on a third gen should be plenty. But you may want to bump it up a couple - u look like you have some healthy mods. How low can you pull it?

I have mine set at 20 psi on my AirDog no issues

I'm just setting it up now I can pull down to 0 on the stock lift pump! I'm sure I'm starving the system! However my rail pressure seems to be holding up at least for a while!

Yea, that's not good... That's how I killed two lift pumps before I got the AirDog installed. Start saving your pennies!
