That's what's nice about a turbo boost/vacuum gauge. Yes, boost causes positive pressure in the manifold. That is how additional air is introduced to the cylinder, rather than relying on vacuum to draw the air in.

The 850 turbos all had a turbo boost gauge in the instrument panel. 'old' cars had vacuum gauges that were calle fuel economy gauges, the higher the vacuum the better the mileage.

Glue? yuck! I would use a small zip tie :)
