I love having one, it is a nice part of the cross-check, does work as an economy gauge of sorts, wastegates do fail and stay closed (or open), and if you feel that your performance has changed it is a good reference to see if you are generating the boost that you expect. It becomes much more useful with a pyrometer/EGT gauge however even stock, which will tell you if for example your SOV is clogged and you are getting boost without enrichment.
Regarding the left vent to access the speedo cable, I have found in my 190Dt that I can pull the cluster out just enough to reach it with my fingertips and remove/install the lock ring on the cable end.
