I understand that the wastegate is the piece of hardware that limits the amount of boost. I understand that the BOV lets the boost go when you let off the gas. How do these electronic boost controllers (like the Blitz one Mike has) work? It would seem they would have to modulate the wastegate somehow in order to let the boost go higher. I've read that the Blitz one fools the computer somehow, but in talking with Mike Jez, I understand that the stock BB T25 has a built in, spring operated wastegate. How does the Blitz boost controller up the boost level?
