i have an '08 crossbones, all stock except for cycle shack slip-ons and SE air filter... the dealer installed them and tuned with a SE tuner, back in 2008. if i buy a SE heavy breather and d&d fatcat (or thunderheaders 2-1) the bike will need to be re-tuned, right? does anyone know if they make a map the dealer can just upload for this seemingly common mod, or would i have to pay $$$ to have them tune the bike on a dyno? anyone have a ballpark figure for either uploading a map or dyno? thanks

 

If you change the pipes and A/C you'll have to re-calibrate the bike. I have the HD Screaming Eagle Performance Tuner. It'll set you back a few hundred.

 

At least a few hundo at the dealer for a custom tune... Bike runs strong, smooth and cool, relatively speaking!

 

I would have it dynotuned again...about 300 bucks to do it right

 

thanks guys
