Message	A little background on my car. I have a tt convert, gt2560r turbos, 555cc injectors, Hks bovs, blitz dual sbc bc, nistune reflash, and most other supporting mods you can think of. I'm having a problem holding boost at high rpm. I am running 18psi, which holds fine until 6k. After 6 it falls flat on its face to 5psi. When I zero out the bc the car holds 12psi (spring pressure) all the way to redline. First thought was the bc. Swapped it out for a manual and still have the same issue. Next was the exhaust being too restrictive. Ran it with open test pipes, same issue. Checked for boost leaks, rerouted vacuum lines, and adjusted wg actuator arms. No luck. I'm going to boost Leak test again and try to reroute more vacuum lines. Has anyone had similar issues? If anyone has any ideas, or suggestions I would appreciate it
