I can this for certain: DO NOT go to the Lebanon, Missouri HD shop. They like to squawk how much they know, but they couldn't tune my 08............at all. Still took the $429 though and when I called back concerned the bike still didn't run well and asked if i could have it re-tuned, they said.......and i quote...."well, you can bring it back, but we're not gonna promise anything."
I'm headed to Tampa FL for the proper tune tomorrow.
On another forum, I've heard Robin at Gails HD in KC is very good. Just what I've heard.
