Yea that's where I found the info. That site only gives what's in the title of the post. Just wondering if anyone knows what it is. Prd pgm? As the website doesn't give any further info.
I think "PRD Pgm" is Harley-Davidson speak for product recall program or something similar. The "calibration" is the subject of the recall. Your friendly neighborhood dealer should be able to fill you in on the details.
