96ci harley performance upgrades?

[frank]

hi, i have a 08 streetglide i would like to get as much power out of as i can without cracking the engine open. I have bassani slip on's already and plan on running their head pipe. what is the best fuel management system? whats the best air cleaner? has anyone switched their throttle body? If so was it worth the money? thanks for your help and keep it shiny side up
