No. (Especially if you don't have an aftermarket turbo timer in the first place.) When you drive your turbo gets hot. When you drive hard the turbo gets very hot, so hot that it actually glows. See for yourself some time -- drive the car hard for awhile and when you get home, open the hood and look down where the turbo is and you'll see a glow. Obviously this is easier at night.
Without a turbo timer, in order to prolong the life of your turbo, you should run the engine for about 1.5-2 minutes at idle in order for the oil to continue to circulate and to cool the turbo. Otherwise, the oil gets cooked pretty bad in the scorching hot turbo and it eventually will lead to an early demise of the turbo unit.
A turbo timer allows you to turn the key to the off position and remove the key, lock the car and go on your way but the engine will actually idle for awhile on its own and then shut off. Different turbo timers work differently: some by a preset timer and other by monitoring your driving to determine how long the car needs to idle.
