Hello

Have a 2009 Heritage. Have put on the heavy breather air filter and the dealer did a download. Have purchased Vance and Hines slip on long shots. Do I need to add a power commander or fuelpak? Or are those pipes OK with just the factory download and filter/ Cheers

Depends what the dealer down loaded do you know if it has SEPST ? If it does you are ok I myself like the HD product very easy to use and you can tune it to your liking.
