Turbo Timers are beneficial to turbo and na cars alike. It adds life to your turbo and engine as it lets the oil cool before becoming stagnant. They are ridiculously easy to hook up also. One wire goes one side of your ignition wire, one goes to the other side, and then ground. It'll work fine with your alarm system, providing you hook everything up right.

You don't have to sit in the car and wait for it to turn off, leave it in neutral, snatch the e-brake, and get out.
