Kurt,
We're planning to have another dyno day at Dave Goerend's transmission shop in NE Iowa sometime this summer - hopefully. We had this event in May of 2001 and 2002. It's been pushed back this year due to dyno changes Dave is making. Watch the WI events forum for an announcement when the date is set. Also, I wouldn't be surprised to see another dyno day at K&S in Wausau, WI in the fall. They had us there last fall and this spring. Both events would be a bit of a drive for you, but not too unreasonable, I don't think. Also, JohnE has a lot going on closer to you in MN - they seem to be pretty active over there.
Dave
