i've never really heard of anyone doing a wastegate/boost controller on a procharger i don't think it's even possible. i tell everyone this, boost is just a measurement of air restriction. say a 3.10 pulley makes 15 lbs of boost, on a car that has same setup with ported heads it might only make 13lbs but more hp... i'm running a 10% OD and a 2.9 RR 8 rib pulley (8 rib setup on a D1sc) now i'm in the 20# boost depending on temp. outside but i have ported heads, cams and so on.. someone with the same setup and non ported heads would make more boost.
the only way you can change your boost output/input is changing the pulley. which means belt and all... personally i daily drive my mustang the way it is, my compression was built 8.5:1 so i could maintain highest hp numbers on 93 oct. just food for the thought but inless they created something i just don't know about and google is failing to show me i don't think you can run a wategate on a procharger
500 hp is all you need to break the 10's.. 500 good suspension and tires.. i've seen a guy in a 93 gt pull a 10.39 on 512 hp so just keep that in mind also
