My own experience... It doesn't help in the rain. My car will still run like a bag of rotten asses. The car runs just fine into the rain, then after it cools off to ambient temps and is restarted the condensation in the charge pipes makes the car spit and sputter. After that it needs a day or 2 of normal driving to clear out and it will be fine.
Install wise its not hard at all. Find something to plug the MAF bung in the intake tube, I used an old blown MAF sensor, fits perfect, who'da thunk it right??? after that just split the black plastice tube crap enough to get the MAF harness to where it needs to go. I zip tied the wires up so they wont get caught in the fan and it works fine.... when its dry. Also, I didn't need any extension harness or anything for the MAF wires. There is more than enough in there to go around.
Honestly its kind of a worthless mod unless you have a BOV that vents to the atmosphere.

I figured by the time the air gets to the MAF which will be right below the TB the moisture would be diffused a lot more. The only time it got wet was when we were road racing in a heavy rain. I have the 2nd design AEM Long Tube intake and the Air cleaner and Maf are fairly close together

Hmmm well it still needs to be tuned. The higher air velocities when the car is in boost will show massive amounts of airflow and throw you into limp mode. At least that is what happened on my car. Maybe yours is different but my LNF definitely needed a tune when I moved my MAF sensor

I hate the MAF relocate. That sensor was not designed to see boost. All it has is a crappy rubber surround and two dinky screws on opposite corners. It's a boost leak waiting to happen.

Personally witnessed two boost leaks coming from the MAF relocate on two different cars. That rubber gasket was designed for vac sealing. Constant boost on it can't be a good thing, especially with two little mini-mount screws on only two corners. I know everyone says they don't have issues, but have you boost-leak tested it lately. I bet you have a small leak there.

I put one on a car here. It ran good until the condensation started to come in. I would tune it and it would run perfect then the next day after a little rain or sitting in the parking lot it would misfire. The maf Hz showed crazy spikes and would go super rich then lean then back rich and sometimes would just misfire for the hell of it. He would then come back to me saying the tune is off, so we would make about 5-6 pulls and it would go away for a few hours then come back. We gave up on it and put the maf back in the intake, havnt had a problem since
