My IAT is in the neck of the filter inlet, therees a (U) shaped cover over it- it was turned so the air hit the cover and went around it, leaving the temperature wires blocked from direct flow, I rotated it so the incoming air would half to flow directly across the wire.
On the MAF, it was on the side of the intake tube, I first rotated it down 45 degrees, didn't notice much, then rotated it up 45 degrees from the original position, thats where I noticed a great difference in the trucks power.
Now I know this sounds crazy, But I remember from my youth, lol, reading books on horsepower by Smokey Yunik, and he always said you half to look at the smallest gains, ( a horse here, a horse there) to end up with something B_A_D,
I can only speculate that the air draft each intake creates has a sweet spot for airflow, a draft path that the air follows, and getting your elect. sensors, meters, and what not in to dirrect line with that path MAY produce the best readings, and then you get the best performance.
You think I'm insane don't you, LoL??

I don't know man...I think it is in your head. You aren't going to feel a couple of horsepower SOTP (Seat of the pants), and that temperature sensor is going to read the same temperature no matter how it is turned. If your codes cleared up by doing this, then you must have touched something else which chaged things.
