However, you won't see the power gain that's available unless you rejet.
My slip-on/jet combo is worth better than 10 hp. I'd say that's significant.
EFI bikes compensate to some degree, making a remap less fruitful than a rejet. Again, I didn't say you MUST rejet, just that you make more power if you do.
