I have a question for Glider mainly but anybody that knows. I currently own a XL1200C but am looking into a 2009 Super Glide. I want the dealer to install SE2 mufflers on the bike. Is there a simple program change they can do to the stock ecm to richen up the fuel mixture or do I need to have a power commander or something like it installed. I've read the reasoning on riching up the mixture and agree. My 2008 Sportser with stock mufflers runs lean enough as it is. I've had one dealer say power commander and another that says they can use a download from Harley. Any advise.
