I have an 07 stree bob and have ordered the Rinehart 2-1 exhaust and the Arlen Ness Big Sucker Stage 1 Air Cleaner/intake from my dealer, as he met the online prices I found, which I found interesting. I was planning on just doing the HD fuel map download. Is this a mistake? Should I scrap the HD fuel map download and get a Power Commander III or other fuel management?
