Perhaps because the PLX is reading from a lower spot on the engine whereas the OBD is reading from the sensor at the top, rear of the engine. It could also be the sending unit I am using for the PLX isn't accurate. I don't know and it really doesn't bother me.
The ngauge is in the ac vent and the PLX is in an A pillar pod with my eboost2. They look out of whack in the picture but are straight when viewed while driving.

Is the ngauge difficult to install?
