I think the Garage 56 kit really needs access to a dyno to set up the ECU. I just don't have access to this. I had the same problem when I fitted the Yoshimura cam/intake/ECU/exhaust kit to my Yamaha Raptor 700R sports quad bike. In the end I had to send the ECU back to Japan to have it pre-progammed. The ECU from Krazy Horse comes pre-programmed. I am waiting for Stuart at KrazyHorse to get back to me with pricing and delivery details. The Millers CVL additive seems to work surprisingly well for the time being.
