Mod to Stock Exh with EFI : V-Twin Forum: Harley Davidson Forums

Looking for info on changing the stock air intake with a K&N high flow and staying with the stock pipes. Adjustments to the stock baffels to gane better flow and sound. Recomended Map for this mod. Made Mod to pipes by putting 2 3/8" to 1/2" holes in chamber plug. Sounds much better. Had the 10000 mile and ask for the K&N filter, none in stock. Going to order online. At that point will I need to re-Map.

You will need some adjustment to your map after air cleaner and dealer will want to give you generic stage 1 flash for $150. And you will still not get best power out of the bike and may start popping on deceleration due to lean map harley uses. My suggestion is to save the money on the reflash and use it to but your own efi module (DFO, TFI, Powercommander, etc.) and you will run better and will be able to tune if you go with future mods.
