When were you in Florida? When will you pass by Carolina again? I feel left out....
Ok, so you've identified one possibility, bad switch. I don't think this could be a clogged intake. Other possibility: turbo waste gate failed, and you do indeed have an over boost condition, and your Pistons will MELT. Need to get a boost gauge to test that theory. Last, the over boost solenoid is faulty, and shutting off signal to ALDA when it shouldn't.
