sure, but I would say you are wasting your time doing it, since the arflow gain would be minimal, and you still run the risk of low-speed issues.
though to be honest, I'm really not a big fan of a/f "computers" like I mentioned above, since they function completely by "lying" to the PCM trying to manipulate it into doing what the a/f computer wants; that and they offer zero help on ignition timing.
a custom chip by a knowledgable tuner is probably the best available solution right now.
