im running bigger injectors. and i was wondering if i needed to wire a restrictor box to the injector harness, and if so were do i get a diagram. ive googled it and had no luck so dont post use google.

 

It doesn't matter if the injectors are bigger, that's not what determines if you use a resistor box or not.What determines that are the injectors resistance.

So my questions for you are what resistance injectors are you running high or low? Also what year car is this build for?
