Another Dyno Question

[Roosell]

I am going to have my 2003 Boxster dyno'ed Saturday with a group of Mustang enthusiasts / friends. Are there any non-intuitive or unusual things to watch out for or do with this car? Any odd anchor points, obscure safe-mode to over ride, or special handshake you have to do? I've seen experienced operators do silly things like dyno a sportbike with the engine management computer set to "rain" because of a lack of familiarity with the vehicle. I know the shop knows how to operate their dyno, but they don't know my Porsche. Is there anything special or a-typical to dyno-ing this car?
