When do you have to change fuel mapping?

[WillowAce]

At what point of adding horsepower should you change fuel mapping? I'm running Bikeman exhaust, going to do the Stingray air box mod this weekend, and putting the Big Venom clutch kit in. Is there any benefit to adding a fuel controller at this point? I don't think I have to change my mapping, but would it make a difference when telling Lonn my base setup?

Need one. Won’t hurt sled short term but mods will be waste of time without adding fuel in some areas.
