This may have been covered already, but how are the two devices (MSPNP and the gauge) connected? Specifically, do they both have individual runs back to the engine, and if so, what two points are they connected to?
There are certain places under the hood where you can get a signal that will show vacuum but not boost. The large hose running to the brake master cylinder is one such place. It contains an internal check valve (barely visible as a lump in the line) and if you teed into that line after the valve to run your gauge, you'd get exactly the symptom you describe.
That said, I agree with the others here in that mechanical boost/vac gauges can be fickle beasts. You should be able to generate at least a pound or two by blowing into the tube- that would be a quick-n-dirty test for you.

Damn it. I followed the Begi instructions to the letter. But didn't think much about what I was doing...I may have put the vacuum block for the guage and the recirc valve on the wrong side of the valve in that very hose...going to check it now...damn damn damn....
I cut that check valve in half when I installed the turbo. $26 bucks for a new one...may possibly be another $26 if I placed the vacuum block on the wrong side.

Does the car feel like it's making boost?
The tuning continues...or rather really starts

You have an .XLS file that is your log, yes?
At the windows desktop (or wherever the file is), right-click on it and select "Send To -> Compressed (zipped) folder."
This will produce a .zip file which is smaller than the original (usually by quite a lot). Subscribers can then use the "Attach Files" dialogue below the message entry window to attach a file to a message. Don't forget the MSQ file.
