I was starting to think about that as well in an effort to warm up the intake air. Having finally read through the entire thread (whew), some interesting discussion. I just found the wiring diagram for my truck's EGR valve, but haven't examined how it actuates yet. As I mull over what I read here, and the fact more throttle opening would be required, this might actually be useful for me to test. My truck is aerodynamic enough now that I find it hard to feather the throttle without making the fuel flow go wild.
I'm not too worried about the IAT, but am a little hesitant with the plastic air filter box and plastic intake... I guess if one were to use a second EGR valve that routed its exhaust to the intake tract, in the center of the incoming airstream, maybe that would work okay.
@mechman60, interesting idea...
@mario, curious to see how the testing is going.
