Well like I said normal temp as i'm slowing down to a stop is around 400, and by the time I stop completely to park it's a lot cooler. Most guys who are driving normally aren't going to sit and let it idle just to lose a few degrees. It's not going to hurt anything. I've read from a few reputable sources that turbo technology is much greater than it was years back and the cool down time isn't as necessary as it was back in the day. Unless i've been running it hard or I notice the gauge is pretty warm.....i'm going to park,shut it off and get to my business.
