Yes, it is fairly accurately measurable if the test conditions are setup properly.  It is very easy to overstate the replacement effects as "great" and/or understate the OEM effects as "poor".  Just know that while driving at a steady throttle speed for 10-15 minutes that the IAT2 will usually run about 10-15 deg warmer than the ambient at IAT1, which is the air entering the turbo inlets.  This is pretty much as good as it gets.  If you measure IAT2 against the ambient outside temp, it will usually run 20 or more deg higher.  If you understand where the temp sensors are located, it makes perfect sense.  If you want to manipulate the numbers to sell a product, it is quite easy to do as well.  All while showing the actual numbers to the customer to show "legitimacy".

IAT2 temps make more sense now that I know where the sensor is.  Curious how much those readings change with and without a tune no matter who's IC is being run. 

Also now this makes a little more sense that Masimoto only advertises a 10 degree drop in temps with their IC.

I don't have the truck today but will be driving it to work tomorrow.  I'll do a little more experimenting with temps and report back.  Seeing what you guys are posting temp wise doesn't add up with the variations I'm seeing from ambient to IAT2.

I'm sure the 170 t-stat would have to have at least a small impact on IAT2 temps since it's in the manifold, right?  That's 40-50 degrees cooler than the stock t-stat.  I'm just not sure that running with engine temps that cool is the right thing.  I'm considering maybe a 190 but want to see if I can find any info regarding what temps are safe or ideal for these motors.
