Careful with just turning up the boost. If you're tuned for 9psi the car might not react well to seeing 12. You can try it, but scan for knock and make sure you're AFR stays safe.
The Boost controller should plug into a vac source and then into the top of your WG. Make sure you read the instructions thoroughly. I've seen people install boost controllers and then all of a sudden they're running double the boost they were before, could blow it up.
Meth is a great idea... You won't need 60s unless you're aiming for over 400whp and you can leave everything else stock.
When you start making a lot of power you might want to look into bigger injectors/pump or if you decide to run e85.
Good luck!
