Default Airdog 150 only running 5-6psi?

Ok so I hooked my fuel pressure gauge up to the factory fuel filter bleeder. Using a Glowshift gauge with a electronic sender unit in te bleeder port. The truck runs strong but it is only reading 5-6psi? And will drop close to 2-3psi WOT, which I know will happen. But shouldn't the pressure be atleast 8-10psi? I put a new fuel filter on and waiting for my Airdog filters to come in so I can change them aswell. Would a dirty AD fuel or WS filter make the pressure lower? I am contemplating on stretching the spring some if the filters don't fix the issue. Good idea?

My AirDogII 165 came with the pressure set at 11-12 psi according to my gauge. Gauge seems to bounce around a little, but no more than .5-1psi.

Yes filters will lower psi a little. As long as you have positive pressure at wot then don't mess with the ad.

I have been through three glow shift fuel gauges in the past year. I just got a replacement in the mail 2 weeks ago and it started bouncing around this weekend and is now stuck on 30 psi all the time. Pyro and boost have never given me probs, just the damn fuel gauges.
