I have a 2008 ultra classic with rienhart slip ons and an arlen ness big sucker air cleaner and I just reccently added a vanson hines fuel pack. I tried the settings that they give but at first bike didnt seem to have enough get up and go so after talking with Derrick at VH he had me changed some of the settings. Now I am getting a back fire pop like it is loading up. I am looking for suggestions from anyone who is running possibly the same set up and if they might let me know what their setting numbers are. Thanks.
