i have a 92 civic and have installed a cold air, header and exhaust... do i need bigger injectors to get a better fuel/air mixture or to progam my chip/new chip to dial it in? any advice is appreciated. thanks

 

You'll want to disconnect your negative battery terminal for about three minutes. Reattach it and turn your car on. Let it idle for three to five minutes then drive as usual. This is known as resetting the ECU and it allows all the electronic constituents of your engine to recalibrate (to a degree) with your modifications taken into consideration.
