I was wondering if I need this box.. I was told I do because the resistant on my injectors was not right. This place put it in before they did my custom tune. I think me car is running rich and I don’t know if this box is the problem.. The box has 5 wires all red with black stripes and it is plugged into a connector with 5 yellow wires with black strips…. what I have.. I am running the custom chip/program in my 92 civic with a 99 accord motor (F23A1) with IPT injectors.. If you need more info let me know
Thanks for your help

 

it's a resistor box, yes you need it, what size injectors?

 

i really dont know all i could see on the injectors was IPT.. i think there stock
