My harley runs like crap& I want to know what exhaust and what tuner has the best tech support and what air cleaner should I use is this stuff hard to put on

 

Maybe you could provide a bit more detail.

What do you mean it runs like crap? Low end...upper end...somewhere in the middle? Starting, idle, cruise, accelerating, mpg???

What, if any, mods have been done?

 

Fullsac Exhaust and he sells the TTS tuner as part of his exhaust package.
