How would this effect overall pressure after the MAF, and engine performance?

Sorry I'm still learning. I want to make very educated decisions before I get my car so I'm ready to start when I get it. I'm a computer scientist with a math minor so I'm guessing the math part won't be overly difficult for me.

I have talked with my wife about it and I might try to reverse engineer the ECU if I get bored. Which would of course let me flash my own firmware onto it

What is to prevent the sound of the wastegate? The wastegate doesn't really make any sound. It's just a valve. What makes a ton of noise is if you vent the wastegate to atmosphere because it's like a direct path from your engine to the outside with no muffler in-between. It's running a portion of your exhaust open which is LOUD.

I can't really answer your second question because I don't know that it makes sense.

I don't think you are going to have any luck reverse engineering the ECU so I would spend the time learning basic turbocharged engine operation instead. Luckily most of the kits out there are already well engineered so you don't really need to make any educated decisions about wastegates or BOVs.
