Hey harley, let me chime back in with my opinion, when asked for it, I give it freely, not as fact or the only way. When I build a custom fuel map it is not much, if any different from Harley's on the lower throttle settings, it maintains stock like fuel mileage, where I pump up the fuel to it is at WOT and a little extra above 3,000 rpm, that is where the extra fuel is appreciated by the engine. Fuelers are fine I would never use the word excellent, but it is a alternative. I had a bike come in last summer that a aftermarket shop installed a fueller on and it was heating up to the point the engine management system was trying to cut the engine out to save it self. that was not warrantable, installed a sest (just installed the factory built map) and customer is still happy and so is his bike. My opinion is Harley's maps are on the lean side but not ''too'' lean or stock bikes would be dropping right & left. Would you install a fueler on a stock bike? Do you need to? The stage 1 download is no different, while it might be a touch on the lean with all mods in line with what Harley built the map for it would be my personal choice. Injector wires are very thin and moving them around too much could possibly cause one to break inside the plastic housing making a simple problem hard to find. When you increase the fuel using a fueler it is flat across the board not just were it's needed, there's just not enough adjustment there for me. Though it can be customized to a individual needs that depends on who's doing the adjusting and what the needs are, it's pretty generic. I do know TFI's are very popular on this forum and it's great because if anyone has questions, someone here been down that road. I just like to explore all the alternatives openly, If fuelers work for you that's great, but the thing I like most about this forum is hearing everyones opinions (why they think there's is best) and that gives me the tool's I need to work with, to make the right decisions for me.
