I don't have turbo timer installed yet, I just wanted to verify timing before turning the car off.. After longer drives I let it sit for 1:30min and 30-1min for average drives.. Also, If i happen to be driving in vacuum way below boost at the end of longer drive, do i really need to wait for longer than 30 seconds?

or how should i go about things until getting turbo timer installed..

Thanks
