This is a great site with lots of good info! Just bought a 2009 Soft tail custom. This is my first Harley. I ordered Bassani pro street pipes and a Cobra FI 2000r digital fuel processor. I have not ordered a air cleaner yet. Couple of questions; How difficult is it to install and set-up the Cobra unit? Am I going to see an improvement in performance with-out upgrading the a/c? Thanks for any input on this.
