Okay guys, I've been reading from time to time about TFI etc. When we bought our Limited we did the Harley Download etc as part of our purchase. What does TFI stand for, and what does it do to make it better than the download? If I spend the coin, what will I expect the outcome difference to be? In other words, since I've done it the H-D way already, is it worth the extra money? I am closing in on my 1,000 mile tune up right now.
