Default Boost problem!!! Please help

<center><img src="http://pictureposter.audiworld.com/67031/audi_crest.jpg"></center><p>Hello everyone, I use to be on AW years ago, but been really busy with school lately.
Anyways I need all your help figuring out a problem I'm having.

2001 a4 1.8t fwd

The car seems to be running great, just like how it would when it is boosting normal, but when in gear and driving it does not show any boost on the gauge. Yet when I rev the car in neutral the gauge detects the boost and it reads like normal.
I disconnected the boost gauge, put my finger over the vacuum line and I feel the vacuum and boost when I'm in neutral. But when driving I only feel the vacuum.
But the car seems to be running fine with sufficient amount of power.

Please help not sure what it can be.
