Can HPT do active tests, such as increasing and decreasing injector duty cycle? It would be nice if you could decrease fuel and see how the sensors react. Are there any pending or current codes? Maybe you have an actual rich condition, or the sensor is plugged in incorrecty like BlackGMC mentioned, and the PCM is compensating by richening the mixture, giving you the .9 reading on B2. Does the plug for the rear sensor stretch far enough to get it plugged in wrong?
Sorry for all of the questions, trying to gather enough info to help

I live in a duplex and have no room for any more tools, it really sucks not having a garage, let me tell you.
I do not know enough about hpt but I am pretty sure you are correct that B2 is compensating. My forward O2 is back way further than stock, in the collector (LT's) so I think it's entirely possible.
