Hi All- Looks like I will be putting my car on a 4wd dyno this weekend. There is an open house on 11/8 at KTR performance in Ayer, MA. Found out about this on (gasp!) Audiworld forums 2 pulls for only $65. I have never had any of the car's I've owned dynoed, any special precautions I should be aware of? Cheers, Riff '95 S6
