I have an 06 street glide with cams,intake, v&h dresser duals, and kuryakyn crusher slipons. I had it dyno tuned with a power commander 3 after all the work was done and now I am thinking about switching out the kuryakyn crushers for a diffrent set of slipons.

Will I need to pay for another dyno session or should I be ok?

 

There's no easy answer to that! You may be lucky and the change have no significant affect, however if you do get a new tune, from the same shop, it shouldn't take them long IMHO.
