Not sure how far you are from Fargo (Sabin Mn) but the SDR guys run their Dyno most all winter. Keep in mind they are generally about two months out on appts. As you have discovered there are not a lot of Dynos up in our part of the world so they stay super busy. You end up deciding to do a few pulls let me know and you can use my shop as a base camp and I can shuttle you back and forth as they will likely have your car most of the day. Many of the FABO guys have wandered into my shop on occasion, Winters are long the bar is always stocked!
