dynotech did some testing on the boyseen reeds compared to stock reeds on the 12 etecs, since they truned up the fuel flow on the 2012 ecm upgrade, the extra airflow of the boyseens gave a nice perk in hp over the stock reeds, aslo was a nice gain in having timing increased a few degrees... both added to 7hp... stock reeds and just timing was half the gain
