c90 "best Bet" performance package
 

2008 Suzuki Boulevard c90t.
Perhaps you could help!
I've upgraded the exhaust to a Cobra Side Cut system. What I'm considering adding is a low restriction K&H air filter coupled with a fuel management hook-up. What would you recommend as a "Best Bet" engine performance package?

Many Thanks in advance for your feedback :)
