I'll be nice this time. That 240's gotta be stolen or a joke.

A boost controller is a manually or electronically controlled device which can raise or lower the boost level on a turbo car (though it can't lower it any less than the where the wastegate is set at). A turbo timer is an electronic device that ties into the car's ignition system and makes the car idle for a set amount of time after the key is removed, allowing the super-hot oil to cool down before shutting down the car. Lower oil temp = less wear on turbo's oil seals = longer-lasting turbo. It's mainly for convenience so you don't have to sit in your car and wait for the oil temp. to cool down every time you get to your destination.
