98 Acura Integra rs

I have made numerous modifications to my engine and got stuck on one particular part. After installing my skunk 2 intake manifold i attached a fuel regulator to have proper fuel mixtures.I understand the too much fuel and too little fuel adjustments can cause problems and actually lose power this is why i am not sure where to set the fuel PSI at. I also have installed crane cam shafts, headers and full exhaust system. If any one has any ideas, that would be great.
thank you.

Dyno and wideband O2 sensor. That is the only way to tune it right. You might want to pick up a SAFC or hondata before you go though.
