Yes we have seen 50whp -100whp increases due to this mod on stock motors from HR to VHR with a tune. All cars have seen decreased spool time and depending on the turbo setup they have seen various gains in their mid-range and top end. Each turbo setup will have different gains but they have all had consistent gains everywhere in the powerband. The company test car saw 50whp with a minor tune. That is a 350z HR with a single turbo and 9 psi of boost.
I will see if I can get some dyno charts from customers to help you guys visualize. The 4.5L is definitely showing an exaggerated affect this plenum has against the competition. Rest assured its one of the best bang for your buck mods on a turbo or even SC car.
