take your neg battery cable off, then unplug the ecm, the three plugs on the passengers side firewall... leave it for about 30 mins, go back, plug the ecm back in, neg hook up, and try again

That seems hardly worth the effort for what little gain you would see, if any.

You can try putting a resonator on the exhaust, this will give you more back pressure which will give back you low end. Downfall is will not be as loud. Drag cars set up their exhaust all the time to compensate for short drags and long drags, (low end and top end power). The more free flowing exhaust the higher topend.

the only way to do it and have it really effect anything is boring the openings to say 52mm and getting the larger butterflies to fill the larger throats... but again you need a better than stock flowing exhaust for this to help with power and not lose torque....better flowing herads are a big plus here too...
