There's a real good chemical available for cleaning injectors and the rest of the fuel system. I don't know what it's called, but it comes in the cheapest and most expensive gasoline you can buy. There's no need to buy more of it. As Wrenchtech suggested, you aren't going to solve a pre-existing problem by adding "mechanic-in-a-can". All it's going to do is make you feel better. If by some slim chance a chemical caused an injector to flow more fuel, (what I assume you mean by more efficiency), the Engine Computer will simply adjust to pulse them open for a shorter period of time. More fuel needs more air which results in a higher engine speed which causes you to ease up on the gas pedal which causes less fuel to enter the engine; so what good did increasing the flow rate do? Very few running problems today are caused by injectors. When searching for the cause of those most elusive problems, injectors are way at the bottom of everyone's list of suspects.
