The manifold temp sensor is a GM IAT, mounted the the top of the intake manifold plenum, next to the map sensor. The other sensor is in the oem MAF. This has been discussed to death on evoM, and its what we all see. Part of the issue is the sensors (MAT) themselves becoming heat-soaked, but once air starts rushing through them they cool down. The important data is near the end of the pull, if temps rise or stay flat. This is a pretty good example of staying quite flat, esp considering its just on the dyno not on the street where there's a LOT more air coming through the engine bay.
If you think this is fuct up, wait till you see what my car does with the alky spraying
