    I installed rush slip ons on my 2012 super glide. It backfires bad on decell. Have a HD super race tuner. Any suggestions?

    With the limited info you gave I'll say the slip-ons leaned out your mixture.
    What size baffles are on the rush's? I put rush slip- ons [1.75] on my Tri, and it would backfire on decell and lose bottom end power.. So instead of changing the slip-on's I added thunder torque inserts and that stopped the backfiring and also increased low end power.

    Get it on a dyno for a proper tune and DO NOT take it to a dealer for the tune. It would be worth riding an hour or two if you have to for a proper tune.:s

    Make sure you didn't introduce any exhaust leaks.
