Yep joel you are right.
Warming up is important of course, but by the time you have been out screwing it and then drive home like a grandma, the turbo would have cooled enough. Unless you are on the track for an hour and come straight off and stop the car, then I would leave it for a few minutes.
I always turn mine straight off when I am driving normally, and it REALLY pisses me off when I see people stop their car and leave the turbo timer going for 5 min even though they have been driving like a grandma. Why don't you get a big sign that says, "I HAVE A TURBO CAR" because basically it is just like that..
I personally like the turbo timers that count up or down on how much you screw it. Mine will go up to a max of 3 min with continued full throttle, if I drive for 10 min without boost it goes down to 20sec, I think that is pretty good.
