Well today I went out to go over to mom and dads and noticed that the truck was running about 36-40psi of fuel pressure????? I am running a smarty on level 8 and it has always run around 22psi and drop a little with WOT. I drove it around to see what is would do and it ran fine. It sounded a little different but the temp outside is getting colder. By the time I got home it was down to 26psi and holding. Could there just be something wrong with my fuel pressure gauge. I have a airdog and the smarty is the only hting that I am running right now. Another thing that I noticed too was that I could only build about 16psi of boost??

Thanks,

 

Unless there was a restriction somewhere due to gelling or some other foreign material in there to cause the restriction. Maybe your Regulating spring in the airdog was cold and stiff?

 

I just went out and started the truck and it is running 26psi. I have no idea why it did that but I guess if something is wrong I will know before long HAHAHAHAHA
