Because they can? Remember, they've got completely programmable spark and fuel with resolution miles past what MS can do. Sequential injection can be used to cool down hot spots and funky things like that but I don't think George is concerned with that level of tunability...

Unless you're going direct injection, I see no benefit above a certain rpm. Do the math; at 1000 rpm each injector is firing 4 times every second. At 2000 rpm that increases to 8 times a second. Hard to distinguish when it's on or off above 3 or 4000. The definition diminishes and eventually it's a steady stream anyways. Sequential fire might be beneficial in a pulse-tuned intake up to a certain point...
