I'm looking to add Vance and Hines slip-ons to my '17 883. I know I'm going to need to do the performance tuning. My question is, if I decide to continue to add more performance parts, air intake etc, will I have to use the tuner each time? Or do I have to do everything all at once? And how easy it it to use the tuner ?

Thank you

 

For just slip-on's,just put them on and ride.no tuner needed.

 

Your ECM should adjust for slip-ons and even a stage 1 air box. Any more than that, you would want to look at adding a proper tuner.
