Help with fuel psi.

I just put in ITPs RR kit last week and have the psi. set at 65 psi. My fuel psi is still dropping down to 20-25 psi at WOT. I have Erics Extreme Street tune in now but it does it with other tunes also.
I need help to try and figure this out. Do I need a new pump like the new AirdogII coming out?

Thanks.

I just went through the same sort of deal. Put a high out put pump on and it brings the truck back to life.I went with Fass 95/90 2014 and am very happy with the money spent.I also figured out once the new pump was in that I have a flat/dead spot in my pedal at the 65 mph mark. I don't use cruise control as the EGTs can get out of hand when not paying attention on the highway. What a difference a fresh pedal makes.

The new AirDogII has the regulated return built in if I'm not mistaken. I'm on the list to get my hands on one and yes it will solve your drop in fuel psi at WOT.
