Ok so my iron was in an accident last week. Busted up my shoulder but lets not talk about me. The bike was damaged and i went to harley and just ordered 2300 dollars worth of stuff for it. Now i got the open back air cleaner for it with the SS's. It should be fine to run it with the SS's and air cleaner correct? I dont need the mapping done do i?

 

Yes you do. You are creating a situation where the bike is bringing in significantly more air and releasing significantly more
air...the only way you will be able to add the extra fuel you will need to keep everything copasetic is to alter the ECM.

You can do it with a download or something along the lines of a Power Comander (I won't get in to which is best as it is usually a debate) but you must add fuel.

 

mreed is totally correct on this one. Nothing more to be said.
