How did nitrous get such a bad rep...?

Nope. My experience with nitrous is watching someone else’s nitrous engine eat up pistons in my rear view mirror.
So you've even dramatize this by adding a price tag of 10K to two different Motors?...lol...
So in this one instance did you talk to the guy and he had a stuck solenoid? And 10k in to the motor? Two of them? Same thing happened?...
Or is this you big shot talking about your turbos?...
