Okay, so heres the deal. I have read and read on the different fuel optimizers out there, but still can't figure out what I need. The only mod's that I am making are exhaust and air intake. I simply just want to add more fuel to the bike, I don't want to dyno, and I don't want to mess with maps. Just want the bike to run cool and reliable. My bike is an 2008 XL883. So based on this information, what would you guys recommend? I think its narrowed down to: DFO TFI - though I heard that TFI and DFO are the same product, the DFO is just rewrapped and sold by custom chrome. VH Fuel Pak Any info greatly appreciated!
