V&H Fuel Pak Settings
V&H Fuel Pak Settings
I have 2009 SG with Stage 1 Flash, HD high flow air intake, V&H slash up basic slip ons and V&H dual dresser headers. I bought this bike used and the mapping was all different than what I dialed in at the fuel pak site. I was riding the bike for a while and the rear cylinder was hot as heck. That is why I reprogrammed it. I am hoping the slip ons I have on my bike are just the basic slip ons with duals. That is what I entered in V&H site. It seems to idle better and when I decel it doesn't pop or gurgle. If the pak was mapped wrong could it make the rear cylinder run hot? Base don the picture do the slip ons look like basic slip ons?

I can't see how it would make one cylinder run hot, one throttle body feeds both cylinders.
maybe it's because the front cylinder gets more airflow and is blocking the air to the rear.

Yeah they have Vance and Hines stamped on the top. So its mapped correctly then. It is running a lot cooler now. Rode last night and today its a night and day difference.
