Yeah, they'll wind down when you're not on boost.. All of you people have great reasons for not spending the money. I'm the type of guy that will pull into the gas station under boost, and then jump outta the car immediatly, so a turbo timer does come in handy. I also use it when I want to go into the store, but need the engine to stay running. Or, when I get up to go somewhere in the morning, I can go out, turn on the car, pull the key and lock it up, let it idle for 5-10 minutes to warm up, go take a ****, and she's ready to run when I get back in.

 

I bought one but haven't installed it. I like to get into boost on the way to school, but rarely have time to let the car cool sine I am always late, so I thought it might save me some time.
