Thank you for taking the time to post this!

What is IAT? Intake Air Temperature?

The one thing that worries me (even though I own a TT) is how little technical information there is on this product. I realize that SS wants to preserve some trade secrets, and respect that completely. However I would really like to know a bit more about what their product is doing to my car. I have read their sales literature and from what I can tell, this product raises boost by tricking the ECU into thinking that the intake temperature is different than it is. So lower boost would be cooler intake temperature? Are they saying that they tell the ECU that the intake temp is lower so the ECU turns the boost up? I am confused...

I like the way my car drives with this product, and it feels relatively safe to me. It would just be nice if somebody who knows a lot more than I do (which is easy since I know very little) could explain this stuff to me.
