i been reading about needing a resistor box for injectors and stuff. would i need one for 300-410cc injectors? thanks for any knowledge. extra info: using an AEM rail/fpr on crome.

 

It depends upon whether the injectors are low or high impedance.

 

Injector box needs are not based on size (although higher sizes +660cc are often found in peak hold). Its based on ohms, low ohms injectors 2-5 i think are called "peak hold" injectors and need a resistor box. High ohm (impednace) 12-15 i think are called "saturated" and dont need a resistor box. So check your ohms

 

bump. more info please
