It's reading manifold temp..... which is normal. Sensor gets heat-soaked, since it is screwed into it.

relocating it in a performance based orientation probably wouldn’t help then? And I have to move it anyway for the Hughes intake eventually.


edit: OR what would be a better place for it SINCE I’m moving it eventually anyway. That might be a better question to ask

Any place that it will still work. It really is only effective in open loop anyway. Once the engine goes closed loop, O2 sensors have much more of an impact.

what is the open/closed loop you're referencing to? I've heard the term alot but neve really been able to understand what it means.

Engine runs in open loop until it reaches operating temp then goes into closed loop.

Yeah, essentially what Moparite said. Newer cars/trucks get into closed loop faster due to heated O2 sensors, etc. But, basically, in open loop, the PCM runs the engine based on data programmed into it, in closed loop, the PCM pays attention to the O2 sensors to monitor fuel mixture, and correct as necessary.
