profec B stops working...
the lights are on but nobody's home 
* it looks like it is working, but it is not controlling boost (at all)
* it used to work with the base factory setting (10gain only - no other adjustments) - but would not control boost otherwise (weird, I know)
* the car has been hibernating due to snow - but took it for a run last night (finally a bit of thaw) - no boost control, won't even work in the base setting
* only thing that has changed since the car has been hibernating, is that the battery was disconnected (and reconnected, obviously), and the ecu was unplugged/replugged
* since the unit was installed there has been some odd noises - when it hits positive boost there is a sound of fluttering air (sounds like a leak, but haven't been able to spot anything) - sound appears to come from the back of the unit
any tips would be appreciated

The solenoid shouldn't fail due to heat, as long as it's installed in a sensible location and not right next to the turbos
. You might have another problem, like a boost leak or something - may not be the controller at all.
