Hello!

I just installed a V&H Fuelpak, V&H True Dual header kit, Thunderheader slip on mufflers, and a Doherty Machine Air Intake. I set the Fuelpak to the factory recommended FP-0543 settings. I then went for a ride and noticed that I had a hesitation right off in 1st gear, and a hesitation once I was really rolling on the throttle. I have no decel pop at all! I called V&H and they recommended that I change Mode 1 to 4, Mode 2 to 3, and Mode 5 to 30. After the change the 1st gear hesitation disappeared and still no decel pop but the high rpm still has a stumble. Can anyone shed some info on what I can do to fix the problem with my setup?

Many Thanks,

Perry
