It just occured to me there are a bunch of different snubbers terms floating around. You can use an RC snubber in parallel with the MOSFET or the coil. Having it across the coil will reduce the speed though not as nearly as bad as a schottky diode. You can use the zener method across the MOSFET. Or you can use the schottky diode across the injector (lowest clamping voltage but also keeps the injector on for the longest as well).
I forget if zeners breakdown fast or slow. Maybe Jaguar knows, but you might require an RC snubber in that case (either across the transistor or injector) to keep things under control until the zener breaks down to save the day.
Either way it's easy to add slots for these on a PCB layout for RC snubber, zeners across the MOSFET and RC snubbers, schottkys across the injector and mount the components as needed. Just remember to monimize loop widths and trace lengths for all of them.
