I have 2008 street glide and was considering installing the kn aircharger intake system, I seen this installed on an 09 street glide in a magazine and on kn's website as well. My question is do I need to do anything as far as reprograming the ecm or using a power commander? The magazine or kn website instructions do not mention it. I was looking at an inake system from HD as well and there instructions say you have to reprogram the ecm. I would prefer not to deal with ecm.
