Not sure about what you heard bren wrx, but Ed at Brainstorm explained it to me like this. The divorced waste gate dp allows for better boost control and less restriction. Now my waste gate gasses don't run into a wall before eventually flowing through the down pipe. The waste gate gasses are allowed to flow more freely as well as the exhaust from the turbo. As you'll see from in the 1st graph I gained about 10 ft-lbs and 12 hp. On the flip side, I made peak torque about a 100 rpms sooner with the flat plate dp, if that's what you're referring to?
