your options are to keep pushing at BD (you might be able to install the '16 tune, no mechanical changes have been done to the motor) or to go with an Uprev tune. Cajun B Pipes has been used by several on this site (remote tuning) with great success. This works best if you are doing lots of power adders. (IMS, headers, catback...)I am striking out finding tuners for the '17's. Has anyone found a unit to work on their 17?
