The K&N filters let too much fine dust through and will dust the cylinder walls of your engine. The 6637 filters a lot better and flows more air. Pull your intake tube off the turbo and see if the compressor wheel looks like it's been sand blasted on the edges.

The water/meth is more for keeping EGTs lower, not as much for the purpose of better fuel mileage.

Clay is a great guy to deal with! As far as increasing your mileage, it will get just as good or better, but the main concern is saving your engine.

I know the WMI is good for EGT's but because it creates a steam engine effect, you engine will be a lot cleaner as well, combustion would be more efficient. As well as it slightly raising the BTU's of your fuel, allowing for better combustion as well. I guess that is why some will say they notice a small gain in fuel economy(using electronic gauges, odometer vs distance calculations, etc).
What about Bio-diesel, if you can run a vegetable oil based fuel, you could technically consider that as gaining fuel economy, because you aren't burning as much diesel to cause combustion, just during start up, and shutdown. I've noticed a few of these trucks on youtube that utilize the rear tank as bio, and add a separate fuel pump/filter for it.
paying less for diesel, and practically nothing for a larger quantity of bio would be a win in my book.
The setup would be a determining factor naturally, but would pay itself off relatively quickly, depending on how many times you would fill up.
Let me know if my reasoning is off on this, because I plan to do this at some point down the road.

Because of the Direct injection, or incompatible injectors? I guess it would depend on viscosity, otherwise, you can always get bigger injectors. Most of them I've seen were IDI, hard to find powerstroke videos on youtube. But they all used electric fuel pumps.. Would electronic fuel injection be possible with these trucks? That might mitigate problems of too much/little bio getting to the fuel intake. I've been looking, but haven't found my ECU anywhere, or a place to plug in a diagnostic scanner.. If you could hook one up, you could monitor it to find out.

Your OBD port is under the dash over by the glove box, but there are only a few scan tools capable of scanning our trucks.
