Deadlift volume

Hi! Have completed strength 3 a few times and am happy with the results. Recently I bought powerbuilding 2 because I wanted to try something new. At the same time, I want to increase my deadlift volume and focus on the deadlift forwards. Should I switch program? Can I add extra volume to the deadlift on the powerbuilding 2 program? What do you guys recommend?

I would just run the PB 2 program as it is without modification, as I think what you really want to do is to improve your deadlift and not just increase the volume. I’d try running it as it is first before modifying it.
