I have a 2010 flhtk that is bone stock except for Xieds. Someone just gave me a pair of tunable hooker slipons, but the only info that I can find from hooker says that the bike needs to be retuned. I know they are from an older model, but can I use them without doing anything else? Thanks.

 

You should be fine. Stock airbox still on? Then no need for a retune or flash. The Xied's should have taken care of lean issue already.

I have the Xied's and some rush slip ons, stock airbox, no problems for 28k, plugs look great, bike runs awesome.

disappointing.
