I have the Jack Pot slip on pipes installed and I will have the TFI unit here Saturday morning. I will go ahead with the TFI install but really want to be sure I get the right AC to complete the stage one the first time. Is the Screaming Eagle a decent choice? Do I have to buy the housing as well as an Ait Filter? Lastly will the settings on the TFI change when I add the air filter? Going on a 09 Ultra. Thanks.
