I have a 2004 roadking fuel injected. If I change the air filter to a hi flow do I need to remap it.

 

I have a 2004 roadking with fuel injection. If I use different air filter like a K&N will I have to remap the cycle.

 

yes you will

 

Not trying to hijack the thread but I had a disagreement about this a couple of days ago. My bike is carbed, V&H Big Radius, K&N Hi flow intake Mine has an adapter kit that supposedly swirled the air going in and it is used with a K&N filter. My buddy says K&N has a filter that fits a stock tc88 airbox, and you don't need the adapter kit. Does this filter option, $100+ cheaper) give the same performance and need rejetting as did my system?
