I read the posts on the HP numbers on the dyno and noticed that there were a few that have not dyno'ed their car before. I am one of those. I am planning on reserving some dyno time in the next few weeks and would like some advice.

what kind of things should i play with? what should I bring with me? can anyone list some "lessons learned" so I don't make the same mistakes that someelse may have made. I want to get the most out of my time and money. I appreciate your sharing.
