Jerry, The temp sensor goes before the turbo. I drought you have one from the factory. I think you could find a temp sensor to monitor the air from the CAC, you could do in and out.
Brett, That brings up the question. What does the factory think are acceptable EGT temps and for how long? As you know I am running a Banks Economind Diesel tuner and the Banks IQ. I can run in the first setting that adds nothing and did that on a trip to get a base line. The hottest temps were when I had cruse on and the ECON engaged. The computer would try to maintain speed in the gear selected. I did see temps over 1300 but turning off the cruise and dropping a gear will drop EGT temps.
