I have a 2007 Street Glide.
It came with Thunderheaders, 103" kit and cams. It still had the stock air filter. I have an aftermarket one. Can I just put it on. I assume it has a program in it.

If I need to reprogram it what are my options and cost.

Any help thanks.

 

get yourself a FuelPak from Vance and Hines. This is the easiest way to program your fuel. It is as easy as sending an email to them with the exact components you have installed and they send you a code via email. You input that code and voila. It works flawlessly.
