I think the Freewheeler trike stock runs really well. With that said, I still feel the closed loop fuel ratio of 14.6 from the factory is to lean for an air cooled motor. (We spend the majority of our riding time in closed loop)

I installed the Nightrider FL-Vied-10 units and set them to control the closed loop fuel ratio at approx 14.2 or at the 50% set point. The Trike ran great at this set point no decel popping it seemed to be running cooler and it had a crisp throttle responce. I also tried the 75% or approx 14.0 set point and the throttle was a little sluggish feeling and seemed a tad to rich for my set up. I also tried the 45% setting and found the throttle response not as crisp more flat and had some decel popping. (13.9 to 14.2 are good ratios for the closed loop operation depending on the bike and the upgrades)

My Freewheeler runs real well at the 50% set point or 14.2 ( My Freewheelers set up= stock air box with K&N replacement air filter, stock ECM mapping, D&D 3 1/2" slip on mufflers with the 2" Vortex baffles) The idle and cruz is smoother. The throttle response is crisp and solid and the very small amount of decal popping I had every now and then is gone.

The FL-Vied-10 do exactly what they say and are a cost effective way to increase performance and cooling when a full blown tuner is not needed.

I ran Xieds on my last bike for a couple years before I went to a tuner. Bike ran much better than stock. For the money I thought they were a good deal.

 

I use VIED's on my 2013 Triglide, they have worked well for me. All I have done is air cleaner and slip ons, so I didn't need a full blown tuner

 

i used them on my 12 streetglide and like them. fooled around with the setting and 50% seemed to be the sweet spot.
