The truck in my sig is defueling from a sensor related to temperature. I'm pretty sure its the IAT2 on the hot side of the intercooler. I asked on duramax forum and nobody has replied, I'm wondering if anyone knows what all sensors can make the truck defuel. I'm also wondering if anyone knows what an acceptable range (flucuation) is on the IAT2 while cruising on the interstate, and how much hotter is should be than the IAT in the intake.
