Quick Fuel Pump Work

Hello,
I have a 440 that I am installing a Novi 1500 on at 6 to 8 psi boost.
What are your thoughts on this pump:

From my calculations I should be ok with 70 gph at 15 PSI if I am standing on it and this pump id capable of 20 PSI . It flows 175 gph at 8 PSi so I am figuring it should flow 70 at 15psi.
