Pthomas,
We have been there a few times now. MassDiesel found the place, convinced him to let us use his dyno for an all day event (ask him about that, it makes a good story), and put the first two or three dyno days together.
We have scheduled for us to be there on May 11. Aside from the fact that we'd like to know how many are coming, you can just show up. Mike charges $60 for three dyno runs. He's a helluva good guy, and is getting an adapter (cable?) so that this time we can get torque numbers.
