Default Boost level using VAG-COM?

I am not feeling as much boost as I was a week or so ago. Is it possible to measure the boost pressure using the VAG-COM? If so, under what module, etc?

Default RossTech has links to detailed instructions, but basically you measure using block 115 which gets

you requested and actual readings in milibar. Then you have to convert to PSI (if thats what you want).

Here is a link that will help:<ul><li><a href="http://home.earthlink.net/~cogent001/vw/">http://home.earthlink.net/~cogent001/vw/</a></li></ul>

Except the "measured" manifold reading is actually calculated.
