Motec is a great unit, but really pricey. This option, a small and a large injector is GREAT for a 1,000 hp race car, where the fuel flow change is so drastic that the large bore, is that the right term for a large capacity injector, will not smoothly deliver small quantities of fuel, my engine, altho using 80 to 100 percent of power at most times of operation is not delivering that much fuel that one injector cannot handle both idle and operating loads properly.

btw - one reason not to use the throttle body is for better a/f mixture control, no matter how good i make my intake manifold and how much swirl i put into the inside of it - the a/f ratios that make it to each cylinder would vary too much
