Has anyone had any experience with this mod to the ecm. I called the Dealer here in New Berlin, Wisconsin (Hal's H-D) and they said they new exactly what to do to tune my '03 xb9s with Jardine and K&N. They said they helped develop it. It basically piggy backs the existing ecm they said. It will also require 1 hour dyno time for a total of $290. Since I can't find a race ecm this looks like my best option. Just let me know if anyone's heard of this or used it. Thanks
