I posted a thread last week about this. I talked about how my Black Maxx showed 12-14 degrees differences in temp. Then when I put my truck back to stock, the gauges showed it was 8 degree difference. Then the dealership tested with their equipment and it was never 4 degrees different and never got over 204 degrees. From what my dealership told me, the very early 08's had a lower temp spec for the oil cooler, but late 08's and on were 15 degrees difference on their equipment.
I put my truck back to complete stock for nothing. Its interesting seeing the fluctuations in temperatures going from tuned, to stock, to the ford equipment tests.
Another member recommended I update my tuner, which there was three new updates that may take care of this. Hopefully these updates take care of my rough idle I get sometimes.
Read my threads on it, maybe I mentioned some other stuff about it.
