I just purchased my first Harley. Its a 2003 FatBoy, and its a great bike. If I change the stock air cleaner element to a K&N, will I need to have the Fuel Injection remaped? Thanks, SteveRace

If you have or plan t install aftermarket pipes then yes, you will have to, you can change pipes or you can change air cleaner and not have to get a fuel management program but if you do both then yes, you will have to. Todd
