If your looking for power and have supporting mods, have your car properly tuned with one of the many standalone systems available.
It wouldnt be that much richer until vtec, but yes the intake butterfly system will be un-operable.
if it was that simple, Honda would have done that from the factory. The stock ecu is already pretty well tuned for a stock engine.
