You need to install a wide band o2 sensor and gauge or take to shop that can add one and measure the fuel ratio at idle and wide open. You then new socket the ECU and tune it at a shop or use Tunerpro and do it yourself. Most new injectors flow more than spec so run rich along with chip tuners make them rich to be conservative not to blow your engine.
