Turbosmart just released an Electronic Plug and Play version of their EM Valve for the N55. They have them available in a Plumb Back Version that recirculates like stock and a Dual Port version that vents to atmosphere. No need to to tear your stock one apart, it's a direct plug and play valve. It sounds great and definitely holds boost better under lighter loads.
