Fuel psi help

[work&play]

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.

Filters, then pump. A good stock pump has no problem keeping up with stock injectors.

I changed the filters twice in the last month and a half, once before I ordered the RR and then again on Saturday. I also change them every 10,000 miles so it is not the filters.
Can a pump go with the truck only having 29,000 miles?

My stock pump never kept up with stock injectors and a hot tune, even after installing the ITP and numerous other enhancements to the fuel system. It's barely marginal at best.
