	As always, there are several ways to do everything. I think for your
application and depending upon your need for protection I think a Greddy or
Haltech "extra injector" system would be the best since I don't think this
engine is going to be used to rev high. This system isn't the most elegant
but I think that it will allow you to adjust the fuel level in accordance
with boost pressure easily. The only problem I can think of is timing. I
don't know enough about Ford EEC-IV to know whether it has a knock sensor
or whether it even has electronic timing. But, either way you will probably
need to retard the timing somewhat or knocking will ocurr. Even with a
sensor your just letting the knock control "save your butt."
