...that will process 2- 5V inputs, "AND" circuitry.
In other words, I want both conditions to be met in order to mist, one input is IAT, the other is boost.
Any ideas?

You could hook up a relay to a hobbs switch for the boost, but I don't know if the IAT is a 5v signal. I think other companies have what you are looking for, but I think that DO will be coming out with something you will like soon.

I have factory MAP and IAT, both 5 V scaling.

YOu could use a hobbs switch to flip the relay, with the IAT as the 5v power. But, depending on the weather outside, you may have high EGTs without hi boost, which may not be beneficial.

It would have to be a circuit with variable knob inputs for IAT (50F-150F) and MAP (20-45 psia). It's not for protecting EGT in this application.
