[200q20v] bar: from .1 to 1.8...is this normal?

What kind of boost pressures are you guys seeing with one of these IA stage
3, or MTM chips, which are supposed to give about an extra 50HP. What
reading does the digital boost indicator in the 200 20V max out at? I've got
a Wetterauer chip in my S4, but no boost gauge. The stock S4 has a overboost
mode which gives 2.2 bar I think. I would think these chips should produce
at least that much.

Assuming that stage 3 means that the pressure sensor has been 
upgraded, your dash boost gauge is now almost meaningless. Surely you 
expect that your maximum boost is actually above 1.8 bar, right? Best 
advice: install an analogue boost gauge. Quick, cheap and easy to 
do--except deciding on a spot to install the gauge. Mine's in the 
glove box.
