Dyno Results 993TT + Techart mufflers

The DD seems to be an accurate dyno but I wonder if someone can explain the exact facts of what "shoot out" mode means.
Also, from my experience on DD with 993's and 996's, around 300-325hp at the ground is the normal range. 300hp might be a dissappointment, but that's where it's at and 325 is a great number. 308-310 is the norm. The real trick is to watch the torque -- these engines won't hold more than 520 ftlb or so (for long) but I've seen a car turn 450ftlb at the wheel ... that's surely overstressing the internals of a stock engine.
In AWD mode on a 993, the drive-train loss is guesstimated at 25%. By disconnecting the front, that loss percentage might be as little as 15%. It's hard to put all these disparate data sets into a single picture.
Again from my experience with these cars on this dyno, I think the shape of the plotted line is as I would expect. I think this could be a stock K16 car in reasonably good condition.
As for heat on the dyno, I'd like to hear about ways other people has solved this (short of a lot of fans and noise...)
