I lived with a 06 6.0 for 3 years with a Trinity and this same exact EGT kit, and it worked perfectly, as it has for anyone else who has purchased it from us, which is why I feel there is an issue in the vehicle, or in the wiring.
If you'd like to send the unit back to be checked out, we can do that.
If you'd like to return it, and get another one or another brand, that will work too, the Trinity will accept any 0-5 V input from any popular EGT devices on the market.
We did not create/spec/design or manufacture the EGT, we just put it in a diablo box
