Anything as far as aftermarket air horns?

Boost is resistance to flow. The engine will cycle the same volume of air/fuel through the cylinders and out the turbine at any given rpm, all other things being equal (cam, valves, timing, etc.) Higher boost levels will contain more O2, per cycle of the piston, hence more power.
Intake mods like bigger horns, intercoolers and associated tubing present the same compressor (turbo) with a larger volume to fill/pressurize. So when the system gets going, the engine moves the same amount of air, but at a lower pressure because now the turbo has to work harder to build pressure (boost), so less power.
So more can equal more and less at the same time!

Holy Alice-In-Wonderland analogy batman! . So what u are saying is, by increasing flow, boost decreases due to flowing more air more efficiently. So what if after u upgrade the system and flow more air, you turn up boost with an elbow or whatever else? Then u have more flow AND more boost. Win-win?

Basically, yes - as long as it's cool boost. That's what Dave was talking about with the MAP numbers.
But there's a catch-22. The best way to "turn up the boost" as you put it is to add fuel. And without cool boost that means high EGT.
You really have to think about the thing as whole system if you want go any further than token mods.
