Man that really sucks, hopefully you guys can make it happen this fall. I dont know what all forums you posted on, but you might try posting on dmax and cummins sites next time. I know at our dyno day i posted just on psd sites and didnt get much interest. So i posted on some cummins and dmax sites and we turned out a good crowd (30+ trucks dynoed) for a 1st tiem dyno event.
Oh man, that really sucks. At least I won't be embaressed if I put my truck up on the dyno this fall!! Like Luke aid, see if you can get some Cummins and Dmax guys too, it's always more fun with more friends, lol!
We had several Cummins sites nailed down, several of my partners in crime up here run those 6 cylinder thingys. we need to look at the D- max site next time though.
