ok, I'm new to all this fuel injection on bikes, but word has it that in order to run a different set of pipes and go topless, a guy needs a fuel management system to put more fuel into the engine, (that makes sense). I want to go topless, k&n, and run some sort of free flowing exhaust, maybe just a Vmod or depending on what I can find, maybe a higher end pipe. The problem I have is I have no idea if I buy a MAP, or PCIII, racetuner, flash, or dynojet, frankly, I don't even know the differences. All I need is something to make my bike run properly when I do these mods, something very simple to install, and that I can't screw up. What exactly do I need to buy? Thanks
