if it has a stg1 download in the ecm it may need a different map for the pc?not sure but i would look into it.
I was just thinking the same thing. I sent an email to FuelMoto asking that question. I may just swap out the Arlen Ness for the FuelMoto air filter assembly and go from there.
I agree... Not sure how you are gonna find this out but the map will be different with and without the ecm download. maybe I missed it but what tunner did you get from FM?
I went with the FM version of the PCIII. The person I talked to at FM indicated they were the same things.
