Yes, I think this is typical.  I have a wideband on my S4 (MTM 1+ SW)
and I see the same thing.

Here is a graph with AFR and MAP, the region between full lean
(overrun) and boost is part throttle:

I don't have a graph with TPS handy but it would show the same thing.


BTW, if you get tired of das blinkenlights, this display is possible
with an upgraded TDS-1 and a wideband probe:
