06 vs 07 EFI differences?
What about your performance and mileage?
Is it better than a pot based fueler?
You are entitled to your opinion, but seing as how you have no experience with the product what value have you added here? The guy wanted to know if it would work on his bike. The only person so far that chimed in that could actually answer his question was me.
As far as if it is better than the pot based devices, this one has two extra harnesses that go to the o2 sensors. It modifies the o2 sensor voltage so that the stock computer doesn't try correct for the extra fuel being added. I think the pot based device just has o2 eliminators. It also makes it easier to set since you don't need a screw driver.
Also don't get too caught up in the "Load based" hype. Any device that piggy backs on the stock ecu is load based. All this device does is intercept the signal going to the injectors and modify it to increase the pulse width on the injectors, then in turn modifies the signal coming from the o2's to keep the ecu from trying to correct the richer condition in closed loop.

if you don't trust it don't buy it but calling the product garbage or insulting my intelligence for buying it is laughable at best.

Man I gotta stop screwing around...
going into truthful mode....buy a sert or tts mastertune. More expensive route, yet the best thing to do. the stock fuel map is not really the best situation for performance out of your bike. Sure this thing adds fuel, but, your still on the stock map. What advantage is being on the stock map. there are timing advancements and rpm limits that should be adjusted to see better gains in your performance that this fueler will not address.
Even if you think you're bike is running fine(so it seems), a dyno could prove that you are at a significant disadvantage running this system over the more proven sert or TTS.
Jstreet I did not mean to make you feel like I was insulting your intelligence(very drunk last night and was just having fun)
Of course I have a throttle body on my carb and I know(due to dyno) that the boyesen x-wing works . My favorite part of the x-wing is the much improved throttle response. I can't really notice a couple extra hp and torque, but, I can notice how much more responsive the throttle is. Well worth it. Can you say the same about this fueler system. Can you back up what it did with dyno #'s? Do you have proof that it really is worth the money over a sert or tts. I believe you said yourself this product is what it is. It is an inferior fuel management device.

. If I wanted something fast I wouldn't have bought a harley. "Go fast" money goes into my mustang. I've been tuning fuel injection for years. I have thousands invested in tuning equiptment, wide band o2 sensors, etc. I know the value of a tuner when trying to squeeze every bit out of an engine. That was not the goal for my bike, nor is it the goal for the majority of people on here. Most just want a safe tune, less heat, and good drivability. For the $150 I spent on the TFI it does all of that. And why would I back it up with dyno #'s dyno numbers? Dyno #'s weren't the goal. I can tell you that I can enrichen it to the point of blowing black smoke out the tail pipe so I know it is doing its job as an enricher. I'm not here to get in a pissing match with you, just answering this guys questions. If his goals are to squeeze every bit of power out or plans on any internal engine work later on he should follow your advice and get a tuner that will allow adjuments for VE adjustments.
