1.6 vtec civic

I'm looking for a few ideas on how to increase hp while keeping smog cert and fuel efficiency when i'm not racing. While I was looking I found the Venom Chip which is supposed to give +25% hp in 1000-5000 rpm during increased engine load like when racing and have an on/off switch for doing smog cert and preserving fuel efficiency in non racing conditions. I was wondering if anyone has tried this chip or has any ideas for me.

I sold them here at this store for awhile and we had too many issues with units failing and then we would have to send it off for repair. So we quit doing them.
