Yea, it's strange. Just don't get it. Mine is basically just the opposite of your experience. Less performance and worse mpg. With low funds, may just stick to what I have and try adding to it instead of starting over with new CAI etc.
Still researching on anything I can add to get better performance. If anybody has anymore recommendation, lemme hear em!

There isn't really anything that is cheap. You have improved the air coming in. You could get a high flow cat to improve the exhaust going out but I'm not sure how well it will work. I've heard that Ford put a higher flow cat in the 4.6s for our trucks and that is how they boosted the paper horsepower from the trucks before.
The old saying still holds true even for trucks, gotta pay to play. Going fast isn't cheap.

That's the ONLY way you're going to get more power (noticeable increase). Naturally aspirated gasoline engines are what they are. They HAVE to run at a specific air fuel ratio. There is only so much fuel you can use for a given amount of air. Increase the air, you can increase the fuel. Once you increase the fuel, you get more power. Once you get more power, you get to spend more at the pump on fuel (both more of it AND more expensive higher octane fuel). The cold hard truth is tough to swallow sometimes, but if you want more performance, you'll have to invest in a vehicle with a higher power to weight ratio. Plain and simple.

Opinions are like , everyone has one and they all stink! I have absolutely no problem with my CAI by AFE. I love the whistle as my engine draws in power creating cold air. My exhaust tops it all off as I roar down the road. I don't doubt for a sec that the Gott's mod is great for the cost. I think there comes a point when you have to think for yourself and make the most of it. Everyone has GREAT advice but you are the one buying the products and driving the truck. Just like some guys are Ford fans others like the competition. Do whatever is going to make you happy. No offense to anyone, I only think personal choice is a big player in the game of mods. If you are going to pay for it, get what you want. Good luck! Anything that will provide more air will be good enough.

My K&N CAI was that way, IAT was at least 10 degrees warmer. It changed really frequently also. With the stock intake or Gotts mod it doesn't fluctuate much at all.

And I looked at their "research" and I can find holes that their marketing team made. But since they are not the only ones that fudge numbers and attempt to rewrite physics I dont rank them any higher than anyone else. Their intake does look a little bit cooler and should offer lower temps while driving.
