I'd check the condition of the small hoses. If they are in poor condition you could be loosing a pressure signal and that wouldn't allow for extra fuel to accommodate boost. Especially if the car sat outside. But do check to see if the turbo spins. If it doesn't then a kit is in order. It does sound like you're not getting boost.
I had a boost hose that came from the intake manifold to a connection that went to the alda that slipped off and no boost. Could be something simple like that.
