My new (76 miles) Cobra's boost guage doesn't move. What's up with that?

pop the glove box open..and pull it the tabs on either side so the glove box lowers out of the way..theres a black pastic vaccum line it has a rubber connection..then it goes to the instrument guages where it plugs in to the boost guage...disconnect it there and see if there is vaccum at idle..if there is than id check to to see if its hooked up at the boost guage..and if there isnt..then follow it out and it goes to the drivers side of the motor see if its off the vaccum port there..should only take a good mechanic 1/2 at the dealer to find the problem..id bet the guage and super charger is ok...good luck

I found out it only starts to register at over 3500 rpm. I haven't gotten there yet because I'm still breaking it in (~225 milles so far).
