NO, Bruce's does not do any chassis dyno testing over the winter, as the unit is an outdoor portable item (on a large semi style trailer). in fact, it is currently out be repainted and upgraded for the coming spring dyno season. if you call the shop, just ask for margret, and she'll fill you in as to when the dyno is do back and will be open. Last year it was the first week in March. This year, who knows, as it is all weather dependant.
