Yea in a word..... Dumb.
This mod will only be useful for those that are going maf-less, otherwise you are just making tuning more difficult. The maf would really like to know the temp of the air at the hot wire, and gm did a fair job on the maf as a whole even with the slow acting temp sensor.

I wouldnt move the IAT sensor. GM took tons of time to make sure it works well with the PCM. There is a calculation behind the scenes in the PCM that takes the IATs reading and calculates what the air intake charge will be at the cylinder head/valve, which is what it really needs. Its just hard to get a sensor there.
By moving the IAT sensor your screwing with the location, you screw with the tune/calculation. Now if you were adding a 2nd IAT sensor, it would be OK to move it away where it reponds quickly to show you if your CAI system was working well or not.

Today I relocated my IAT Sensor to the Intake pipe. I removed the 2 wires from the factory MAF connector and spliced in a Delco pigtail connector. I drilled a 1 inch hole in the Intake pipe and installed a Delco IAT sensor. On the initial test drive I noticed a very quick response to temp change on the scan tool. I will need to do more testing to determine real world results.
Connector: AC Delco PT307 GM 12102620
Sensor: AC Delco 213-243 GM 12160244
Grommet: GM 14054892
Wires in MAF, My truck is a 2007 LY5. Check schematic for your specific application. Terminals D and E. Tan, Tan/Black wires are for the IAT sensor.
This is the best hole saw set on the market. A little pricey $$$$!
Here is the Factory Sensor and Connector.
Stock before install.
Hole drilled, Grommet and Sensor installed. I ended up using a different Grommet than pictured. GM part number 14054892 fits the best on a curved pipe.
Wires removed from MAF connector.
I used GM crimp and shrink connectors. I like these because they have a sealing glue that comes out when heated.
This picture shows the GM factory parts installed. A perfect fit.
Finally I covered the wires in conduit. I try to make any mods that I do look factory.
