You are lucky the V&H guys shared that little bit of infromation with you on the first 4 settings, usually they just ask questions and give you different #'s and don't tell you what they are for. They are very helpful. Here is what i did, I ''thought''my muffs were V&H, but, they had a serial # only on them, no logo. So, i go with the V&H up cuts, true duels, high flow AC, Stage 1 download, that's what ''I thought'' i had. Well, it ran, ''ok'', then one day i sat down, went to the Harley parts page, found out i had SE muffs, the other stuff was still the same, AND, the orig fuel pak settings were something like FP# 0389, the REAL ones i should have used were FP 0398 , quite a difference!! My fault, there are a lot of variables, and I goofed, now, it's set right. Just in time for me to reset it, because i have a set of WP muffs coming LOL. One thing the FP is pretty straight forward to set, and the V&H tech's are a pretty good bunch of guys, they'll help you all they can. Just don't be like me, and read the wrong #'s, do a recheck and make sure you have all the right settings.
