11.6 psi is about wastegate spring pressure for those turbos right? Sounds like hi setting just closing off the solenoid, not letting any pressure to your wastegates and they are just holding shut and overboosting. Then lo setting is just opening the solenoid letting "all" the pressure to your wastegates and they are working as if the BC isn't there and working at spring pressure.Do you have the correct ports hooked up on the solenoid? Is the wiring right and good (no bare wiring shorting out)? Been a looong time since I've done anything with my Z or installed my profecB sepc2 First guess assuming your installation is good is that the actual BC is doing something weird and not pulsing the solenoid correctly and just doing both extremes, full open or full shut.
2+2=4; 2+0=2; 4>2 : 2+2 > 2+0. 
Can anyone whos removed the headlights just by going through the turn signal hole, post a pic of their arms? Im just wondering if you have little tiny arms, or if you can somehow dislocate your wrists?...Im not saying im huge or anything, because im not - Ebola 23:10:42 01/20/05
