I'm pondering ways to cram a bit more air into my engine, and with it a bit more fuel. How close to "pegged" is the NA ECU & such on a stock EA82? I'm debating a small supercharger. If I don't run more than a few pounds of boost, I shouldn't need much in the way of ignition tweaking. If it's a matter of the stock ECU being close to pegged out, I could always add a small injector that comes on under boost.

Since the stock fuel pressure is fairly low, you could use a rising rate regulator to raise fuel pressure under boost. You'd probably want to install a turbo fuel pump as well.
