digital boost guage

hi all,
got a problem with the digital boost guage on my 2002 gtp. when you turn the key to run, it self tests fine, every thing lights up and you get full deflection, but after the car is started there is no longer any indication. any one out there have a wiring diagram for this particular dic or know what could cause this. is there a vacuum source that comes from the supercharger that controls this, or is strictly electronic. any help would be greatly appreciated.
thanks in advance.

The lego bricks only move once the car is in boost.

They will be nothing on the little screen until you reach anything above 0 vaccum, so like go romp on the car and see if the lego bricks go up.
 
yes there should be vac line coming off the top going to the map sensor which reads manifold pressure hence translating to boost on the dic or ur boost control solenoid is broken causing you to create no boost hence not reading any boost

should you not still get an indication even if in park and just crack the throttle really quick?

thanks for your reply msk. i'll definitely look into that. i'm sure she's producing boost because when i hammer on the throttle, the response is instantianious!! unbelievable acceleration.
