From my memory it was just before where the 4 exhaust runners enter the scroll for the turbo, so that would be close to the WGA arm nearer to #4 cyl. I think it was said that this was the spot that the Dodge had recommended.
Pit Viper had made a thread with images.....you may need to dig a little to find this thread.
On the other question.
I think Dodge had the engine on the dyno for a long time for development and this allowed them to get things calibrated...such as knock. I think that while they were testing with EGT probes hooked up they were able to correlate some inputs at the PCM to come up with estimated EGT. I doubt these guys are gonna release the data and what parameters enable them to come up with the output they have. From what it sounds like its not too bad to use in a general way.
Questions, I did a search in the service manual and I could not find an instance where it refers to the PCM using this data (EGT) to make any adjustments with.....or did I miss it? Is this a parameter or output that is there and not used or is this info actively being used by the PCM for adjustments?
