YES!!

[chopper roy]

I would like to see how this works for you as I am thinking of putting the Vance & Hines headers with the high output slipons

[Chains]

Yes on the re map

I spoke to my stealer about the same set up and they said yes to a remap.  I think you want to get the "lean" condition corrected and that's why it's recommended but not absolutely necessary.

IMO, Find a dealer that knows what they are telling their customers. And yes, fuel management is a must

Yes.  remap.

The factory system can correct for some changes but one needs to remember these are just coarse adjustments. They will not be able to handle your changes correctly. They will help but not fix it. You may end up with a bike that runs poorly in some areas why it runs good in other areas of the operating range. This is why you need to remap it. Had your modifications been simple slip-ons you might have been able to get away with it, but anything much more than that and it's just not going to happen correctly.
