Do u have PN for the indivitual IAT and does it come with a bung. Also, what to do with wiring it as stock IAT uses the stock maf plug and I don't want to cut that maf plug.

This is my target, to use Dmax 3.3 map and tune it SD mode but I though you said why hassle with 2/3 bar map tune.

If you decide to get rid of your maf then you can buy a sensor like this.
FAST Air Temperature Sensors 30086 - SummitRacing.com
If you go with an iat sensor like that you have to cut two wires out of the maf harness and run to the iat sensor. You don't need a bung for it. I drilled and tapped my intercooler pipe and put it in with rtv and it hasn't leaked in 5 years. You can leave your maf in but I have blown two of them in half so I deleted it out.

I know the difference between mafless (SD) and maf tune. But could he go 18 psi with maf tune?
I already have my maf hooked up before the TB just for IAT sensor and was planning to disable it in the SD tune. So, is it good idea to go maf tune with stock map upto 15 psi???

I maxed out a stock maf on 10psi with a 5.3...I didnt want to bother with scaling so I just went straight 2bar sd on that setup and its been great. If everything is tuned properly you will not notice a difference in table resolution between the 2 and 3 bar. Hell I ran NA for a while on a 3bar sensor. The lower resolution is not that big of a deal.

You can get the threaded IAT from autozone, the number is SU107. But I would also buy the bung. You can actually get the bung, iat sensor, and pigtail all from RPS. Just cut the two IAT wires out of your maf harness and solder the new pigtail to it.
