Do they do anything other then bend a tube to fit and slap a filter on it?

Lol looks like they ran the car on 87 then drained the tank and ran it on 91

Any intake that uses a larger MAF housing requires a tune to compensate for the decrease in velocity. As long as that is done any increase in power will be maintained. Testing restriction by measuring pressure drop at the throttle body inlet is an excellent way to determine if there is power to be gained. Unlike a dyno test which may vary from one run to another, you can do a hundred full throttle runs and the manometer will read the same every time. I will test the factory intake in the near future if the weather cooperates.

Thats the point they didn't mention a need for a tune

That's because the maf housing is the same diameter as stock. BTW, I just happened to read some info on Ford Performance where they mentioned aftermarket CAI's that are larger than stock but use the factory maf transfer function, resulting in a power increase due to lean AFR, just as you said. I stand corrected.
