I had the groaning BB DET BOV syndrome. The thing would groan like a rabid horse at part throttle. It was real annoying and it felt like it was losing power also. Ben if you have this problem with yours go out and buy a BOV off a 91 Eclips turbo. They bolt rite on and I only paid $13.50 for mine!(from the junk yard) They are $110 new from the mitsu stealer.
The new BOV works great and it even whistles when it pops off
The DET's diaphram feels very weak compaired to the mitsu's and the mitsu's also has a presure feed that goes to the top of the diaphram. When under boost it will have equal pressure on both sides giving it a lesser chance of opening at the wrong time(good for spool up). Go get one and enjoy!
