in most cases, and especially to our cars, piggy backs are a unreliable/out dated way to adjust air/fuel ratios.

If you head swap it then you will need to get it dyno tuned. If you're going to do that, why not get an H22 or B18C1? Stick to the OEM ECU as much as possible. There is nothing but crap out there as far as hacking the OEM ECU or trying to get a good tune.
