I'll add a counter point. I put 5.6K ohms of resitance on my IAT and found that in temps above 70 degrees I see a bit of timing advance which, in my timing advance starved ECU, helps a bit for mpg. It's not much of a gain, but it is positive and the resistance change is so small that the ECU doesn't learn it
