Noob here with some questions. (Wastegate, Blow off)

Gauge

This is to prevent the sound of the WG I would think?

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

Again thanks to everyone for answering questions and helping me. I know from experience helping new people can be a hassle.

EDIT: Also for any other noobs reading this post, I highly recommend that book I posted. It's less than 20 bucks and it has very up to date information on turbocharging. It's very noob friendly. You have to know "basically" how an engine works. If you do then the book will guide you from that. I think it's a good book even if you don't want to turbo honestly. You learn about displacement and compression and all that.
