What do you think of V&H fuelpak on a 2005 Deluxe with stage 1 air cleaner and Rinehart slip on mufflers .Any thoughts on what to use with just those mods.

Great first step on making your bike run cleaner and more efficient. You also can make all those changes in your own garage in a few hours. V&H has all your settings for your setup on line

I prefer the Power Commander over the V&H Fuel pack for any mods beyond stage 1. That being said, if stage 1 will be the extent of your mods the Fuel Pack will work fine and is cheaper than the PC5
