Thanks everyone for your quick replys. Went to DB (The guys there are awesome BTW) got a MBC, and a ton of info, got back to my shop, slapped it on, Now I'm off for some happy boostin'
They are just an inexpensive basic ball/spring MBC, not a ghetto bleeder and the adjustment dial isn't overly sensitive. A $100 Hallman is a nicer unit, but there are quite a few bigger name brand MBCs that are junk(Turbo XS, Turbonetics and Forge come to mind).
