DI means Direct Injection of fuel into each cylinder, much more efficient and powerful use of fuel. SFI means Sequential Fuel Injection which means that while each cylinder has a fuel injector they fire into a intake plenum (manafold) sequentially much like Multi point Fuel Injection (MPFI) but which only fires in banks. DI is the only way to go.
