Itís a good read and probably came out in 2014? There were some issues with the scaling on MAF with the original version, so that had to be tuned out and wouldnít work on a stock truck.
Thanks for the encouragement! I tried to find the topic with this in it as I thought it might make for an interesting read. Found a couple topics relating to the 6.7 intakes but none with a dyno test. Any way you could help me find it?

Quick update.
Made a large trip to Texas to bring back a trailer and Farmall H before a lot of the pandemonium. Drove into a headwind both directions. I'm also guessing that all the stations were still running winter diesel based on not seeing anything too different. On the way down I got two full tanks burned at 16.5 and 15.8 mpg hand calculated. I had a tank that was half unloaded and half towing that was 14.8 mpg hand calculated. This tank may have been "summer" fuel but it's hard to tell just from the numbers. The rest of the fill ups back were 10.4, 11.9 and 11.2 mpg hand calculated. Not too different than what I was seeing before the intake on winter fuel. Slightly less but I want to chalk that up to the headwind and higher speeds (75mph most of the time). I hope to get some better comparisons with a tank or two on my normal commute.
Running interstate into the wind I was seeing intake temps 2-5 degrees higher than ambient. Not enough for me to get worked up about but the perfectionist in me knows they could be better. Might be a cheap mod I can do if I end up with nothing but free time, short on cash, and an itch to improve the truck. I see other larger improvements I can make first.
I think there is some throttle response improvement after this trip. On ramp drags and passing pulls seemed improved if only marginally.
I haven't peeked at the filter but I can't imagine it accumulating much of anything yet.
