Boost Gauge vs Electronic log difference - BMW 3-Series (E90 E92) Forum

I was wondering what difference you guys are seeing in boost from your boost gauge vs the logged boost at throttle. I am picking up boost pressure from the diverter valves and noticed that there is a .2bar difference between logged pressure and what is shown on my Rixster Gauge. I am thinking this is a out of ordinary varience so I would appreciate some feedback on what you guys are seeing.

It may be because of your 5500ft altitude ? Maybe the pressure sensor is not so precise at that altitude, even with calibration.
