When do you consider the S4 properly warmed up, and how long to let it idle to properly cool down?

Personally, I don't hammer it until oil is 200-205
which is my normal operating temp when not driving hard and when it is below 80 degrees ambient.
I baby the hell out of it until the temp moves off of left side and give it moderate throttle if necessary before I get to the 200-205 range.
My reason for this is not just for oil lubrication, since I use 0w30 and should be getting flow, but the rubber hoses that carry boost need time to warm up themselves so they have proper flex. Like any material, extreme temperature changes in a short period, with added stress may shorten their life.
I may be **** and may overdo it, but it doesn't bother me a bit.

This why I think it is imperative to get a boost gauge...
Hard to just judge if your turbos are working hard. With a boost gauge, you know exactly how much boost your turbos are producing. One will be surprised how little boost they use as well as the times you are in boost and wouldn't think you would be.
