Unfortunately it's not that easy; the O2 sensor is the last sensor in the chain. It measures the amount of oxygen in the exhaust and compares it to the amount of oxygen in the atmosphere. The only way to get around the oxygen sensor "problem" is to modify it's signal in one way or another. The simplest I've found is the EFIE. Another one (though much more expensive) is the O2ptimizer that comes with the HAFC kit.
I would assume, however, that DV has the equipment to be able to tune to whatever air/fuel ratio and ignition timing that he wants; if that is the case, no external controllers would be needed. Otherwise, you'll have to add the price of an EFIE (or a dual EFIE if it's a V engine) to the install.
