Soooo, here is our shop test mule. It is a 2015 Mustang GT with a Procharger stage II kit with a p1-sc, ID1000 Injectors, Kooks 1 7/8 longtubes and complete exhaust, GT350 Intake Manifold, and a circle d converter. We have officially found the stock limits of the factory fuel pump. Boost-a -pump is on order. We feel that the car should make 750ish to the wheels when we get enough fuel to keep going.
