The primary advantage to peak and hold (low resistance) injectors would be the quick response. Saturated injector drivers can't handle them without current limiting resistors which defeat the quick response. So I was thinking about putting together a simple circuit that acts as a relay so the low current driver can switch high current peak and hold injectors. Not actual relays of course but mosfets.

Would doing this be worth while assuming it costs only a few dollars more to do? Do drivers for peak and hold injectors limit the current once they are open? (that might add to the complexity of the circuit)
