Had a few questions being a new member on this board maybe someone could point me in the right direction. Basically what I'm facing as of right now is my fuel being too lean on stock b20b vtec. This setup includes stock B16a head including manifold, fuel rail, injectors, FPR, ETC. I have a fields vtec/ fuel controller that allows 30% increase or decrease. I am currently running 30% over stock on a B16a ecu, and the a/f is averaging about 15.1 on the dyno pass. Basically what I need to know is what upgrade(s) are NECCESSARY to correctly supply the motor with enough fuel?

 

bigger fuel pump, and maybe some rc 310 injectors. once you upgrade your fuel supply, get it tuned!
