Default How can I tell if my N75 is busted?

I did a search - seems that not many have had the N75 fail on them. What are symptoms of it going whacky?

Default No boost. Or rather minimal boost. If you unplug it & notice no change, it's dead.

I had one go, but it was a preowned 'Race' valve. They seem to be pretty reliable.

Default Smart A$$! :-P

Haven't tried the dealer. But I have a feeling that all they'd tell me is "Well, you aren't supposed to get it chipped or change the DV, or add Modshack stuff, or....." Damn dealer...
