Do I need to Flash ECM on Harley with Stage 1?
Dougster asked: I have a 2008 HD FLH with a pair of Screaming Eagle slip on mufflers and I just bought the matching Screaming Eagle AC upgrade. Will it be ok if I install this breather kit without flashing the ECM or installing a Fuel Pack? I don't want to hurt my engine. What Do you think? Tha
